I have irregular periods, but generally I get my period every 30 days or so. My last period was on March 2nd. I had unprotected sex during my ovulation period. I have very sore breast for the past 7 days, which I do get before my period, I'm very tired all the time, eating a lot and constipation. Should I take a pregnancy test now or wait a little longer and do you think my symptoms could be a pregnancy. Im 36 years old and have two kids, I really want to have another one! Thank you!
