Your period is supposed to start soon, but something feels different. Maybe your breasts are sore. You are more tired than usual. You feel bloated, emotional, or mildly crampy.
Those symptoms can easily lead to one question: Could I be pregnant?
The tricky part is that many early pregnancy symptoms are also common before a period. In fact, PMS and early pregnancy can feel so similar that symptoms alone are rarely enough to give you a clear answer.
There are a few differences worth knowing, but when pregnancy is possible, testing is much more useful than trying to interpret every change in your body.
Both PMS and early pregnancy involve changes in hormone levels. Because of that, they can affect your body in some of the same ways.
Before a period, hormonal changes can cause breast soreness, bloating, fatigue, headaches, appetite changes, and mood changes.
Early pregnancy can cause many of those symptoms too.
That is why a symptom that feels unusual does not necessarily mean pregnancy, and a familiar PMS symptom does not necessarily rule it out.
Your own menstrual pattern can provide some clues, especially if your cycles are usually regular, but it still cannot confirm what is happening.
Some of the most confusing symptoms are the ones that commonly happen in both situations.
Breast soreness or sensitivity can happen before a menstrual period and during early pregnancy.
If breast tenderness is something you normally experience before your period, it may not feel particularly different during a cycle when pregnancy has occurred.
Feeling more tired than usual is another symptom that can go either way.
Some people feel tired in the days before their period, while fatigue can also appear during the early weeks of pregnancy.
Mild cramping can happen shortly before menstruation begins.
Some people also report mild cramping early in pregnancy. Because the sensations can feel similar, cramping by itself is not a dependable way to distinguish between the two.
Hormonal changes before your period can make you feel bloated or uncomfortable.
Digestive changes can also happen during pregnancy, so bloating is another symptom that does not provide a definite answer.
Feeling emotional, irritable, anxious, or simply different from your usual self can happen with PMS.
Pregnancy can also affect mood, particularly as hormone levels change.
There are some signs that may make pregnancy more likely, but none should be treated as confirmation without testing.
A missed period is usually the most useful clue, particularly if your menstrual cycles are normally predictable.
Nausea may also occur during pregnancy. Despite the common term "morning sickness," nausea can happen at any time of the day.
Some people notice that certain foods suddenly seem unappealing or that familiar smells become much stronger. Others may need to urinate more frequently.
Still, pregnancy does not look the same for everyone.
You can be pregnant without nausea, cravings, breast soreness, or other symptoms people commonly associate with pregnancy.
If your period has not arrived when you expected it, pregnancy is one possible explanation, but it is not the only one.
Stress, illness, significant changes in exercise or weight, hormonal changes, and other factors can affect the timing of your menstrual cycle.
If pregnancy is possible, however, taking a test can give you much more useful information than continuing to compare symptoms.
Home pregnancy tests detect a hormone called human chorionic gonadotropin, or hCG.
Testing very early can sometimes lead to a negative result even when pregnancy has occurred because there may not yet be enough hCG for the test to detect.
If you test at home and receive a negative result but your period still does not start, consider testing again after several days or talking with a healthcare professional.
A positive pregnancy test can bring many different emotions and questions.
You may immediately start thinking about how far along you are, whether the pregnancy is developing normally, or what you should do next.
A pregnancy test cannot answer all of those questions.
Depending on your situation, an ultrasound can provide additional medical information, including where the pregnancy is located and approximately how far along it is.
Options Pregnancy Center provides no-cost pregnancy testing and ultrasounds when appropriate. The goal is to give you clear information and time to ask questions without pressure.
You can also read Why Medical Confirmation of Pregnancy Matters in the Options Pregnancy Center Education Center to learn more about what pregnancy testing and ultrasound can tell you.
Most mild symptoms do not signal an emergency, but certain symptoms should not be ignored when pregnancy may be possible.
Seek immediate medical care if you experience sudden or severe abdominal or pelvic pain, shoulder pain, severe dizziness, weakness, or fainting.
These can be warning signs of an ectopic pregnancy or another medical problem that needs prompt evaluation.
If you are experiencing severe symptoms, go to an emergency room rather than waiting for a pregnancy center appointment.
When PMS and pregnancy symptoms overlap, it is easy to spend hours wondering what every cramp, craving, or change in energy means.
You do not have to figure it out based on symptoms alone.
Options Pregnancy Center offers no-cost pregnancy testing in a confidential, respectful setting. You can ask questions, understand your results, and learn what next steps may be appropriate for you.
If your period is late or you think you may be pregnant, contact Options Pregnancy Center to schedule an appointment.
Getting clear information is a good place to start.
