I m trying to figure out what s wrong with my body. I skipped last months period due to stress I believe. I ve had unprotected sex for the past two months. I had all of the pregnancy symptoms in the past three weeks. I spotted a little during sex but it stopped completely afterwards.. I thought maybe it was implantation bleeding. I ve had nausea, cramping, tingling nipples, breasts feel fuller but not a huge difference, my nipples have bumps that became really noticeable a few days ago, I ran out of breath easily when going up and down stairs, hungry all the time, etc but then yesterday I started spotting and it was dark brownish blood. But today it seems like a normal period. Maybe not as thick or heavy. I don t have to wear a pad for it. I took a pregnancy test a week ago but it was negative.. It was a cheap one. I thought maybe it was just too early. I know two girls that still had periods for six months before they found out they were pregnant.. I was CERTAIN I was pregnant but now I m worried. I had sex basically every other day if not more than that in the first weeks of last month. We slowed down when I started seeing all of these symptoms. What do you think is going on?
