When your body starts sending mixed signals, it's hard not to wonder what they mean.

Maybe you're more tired than usual.

Your lower abdomen feels crampy.

Your breasts are sore.

You're suddenly hungrier than normal.

Maybe you've convinced yourself your period is about to start… except it hasn't.

Or maybe it did, but it was lighter than usual, and now you're wondering if it was really your period after all.

If you're asking yourself whether you're pregnant, you're not overthinking it. The truth is that many of the earliest signs of pregnancy are almost identical to the symptoms many women experience before their period.

Why Do Pregnancy and PMS Feel So Similar?

One of the biggest reasons it's hard to tell the difference is because both PMS and early pregnancy are driven by hormones. In the days leading up to your period, hormonal changes can cause symptoms like:

Fatigue
Cramping
Bloating
Breast tenderness
Mood changes
Food cravings
Headaches
Feeling emotional

Early pregnancy can bring on many of these exact same symptoms. That's why symptoms alone usually aren't enough to tell you whether you're pregnant.

When Is the Best Time to Take a Pregnancy Test?

The best time to take a pregnancy test is after you've missed your period. That's when most home pregnancy tests are the most accurate because your body has had enough time to produce detectable levels of the pregnancy hormone hCG.

Here's a general timeline of what typically occurs if you've recently had unprotected sex (or think you could be pregnant) and when testing could be most helpful:

0–5 days: Fertilization may occur.
6–12 days after fertilization: The fertilized egg implants in the uterus, and your body begins producing hCG.
Around the first day of your missed period: Most home pregnancy tests can accurately detect hCG if you're pregnant.
If your test is negative but your period still doesn't start: Wait 2–3 days and test again. hCG levels roughly double every 48–72 hours in early pregnancy, so testing a little later may give a more accurate result if you tested too early.

What if my cycle is irregular?

If your periods aren't predictable, try to wait at least 21 days after unprotected sex before taking a pregnancy test. By then, hCG levels are usually high enough to be detected if you're pregnant.

Are medical-grade pregnancy tests more accurate?

Medical-grade pregnancy tests used at pregnancy centers are highly sensitive and are administered in a clinical setting. While many over-the-counter tests are also very accurate when used correctly, visiting a pregnancy center offers additional benefits beyond the test itself.

If your test is positive, the staff can help you:

Estimate how far along your pregnancy may be.

Determine whether you may qualify for an ultrasound.
