1. MISSED PERIOD:
Probably the most well-known sign of pregnancy, a missed period is an immediate indication that something’s up. But be sure to take a pregnancy test so you’re 100 percent sure: According to the Cleveland Clinic, your period’s disappearing act could also be due to stress, excessive exercise, and dieting, among other factors.
If your period seems abnormally light, it might not even be your period at all: “If you’re pregnant, you could experience some bleeding two weeks after fertilization and think it’s just a light period. Then, once you get to your next cycle, you’ll miss your period,” says Mary L. Rosser, M.D., Ph.D., division director of General Obstetrics & Gynecology at the Montefiore Medical Center.
Because of all the hormonal changes going on in your body during the initial stages of pregnancy, you might experience bloating that’s similar to the puffiness around the beginning of your period, says the Mayo Clinic. But unfortunately, unlike with your period, pregnancy bloating sticks around.
You know how your breasts tend to get sore before your period? The discomfort is taken up a notch when you’re pregnant. “One very common symptom we see is very exquisitely sore and tender breasts,” Rosser says. “They’re much more sensitive and sore than even with regular periods.”
