I had sex April 30. Since then, I have had 3 periods that have been normal (5-7 days and very heavy which is normal for me). I am worried because I have been working out for a month or so now every other day, and I have not lost any weight nor gained any, yet my stomach seems larger. Could I be pregnant? Any assistance is appreciated! I have terrible anxiety and am stressing about the possibilities. So thank you In advance.
