I have been having late periods for the past 6 months(unusual), this past cycle started on January 3rd and the next one was supposed to start on the 29th. I had unprotected sex with my husband on the 23rd and 28th. Missed my period and at the same time started having sore breasts. A few days later nausea. Then a on the 6th started bleeding. Symptoms didn't stop then like usual. Period was lighter than usual, but steady flow every time I went to the bathroom. No much cramping. Very Weird period. Now my period is over but the symptoms are increasing. When I wake up my breasts are ok, but start getting sore as the day goes on. And I am nauseous every time I eat. I have also been having to go to the bathroom a lot, constipated, heart burn, and weird cravings. Took a pregnancy test when period ended but was negative. I will go to the doctor but want to wait a little more just in case. Has this happen to anyone? where you pregnant? Do you think I could be pregnant?
