My husband and I started trying to get pregnant last month. About 1.5 weeks after my last period began we started having sex every day. About a week after we began the "baby making process" my boobs got really big and my nipples were changing color. Also the area around the nipple itstelf looked bigger. I believe I had morning sickness 2 mornings even though I know it's rare to have symptoms that early on. I also had heartburn and I've never had heartburn before. Then exactly 8 days before my expected period I started having very very light brownish discharge or spotting, which I've also never done before. For 3 days I had this very light spotting and on day 3 it looked a tad pink. Then exactly 5 days before my expected period I started cramping and had lots of bleeding as if it were my period but something seemed different outside of the spotting before hand. This is not normal for me since my period has always been very regular every month on the same day unless it's a long month then rarely it will be a day early. My period or whatever it was stopped yesterday and today I had a tad of light brown spotting like before my so called period...?? I'm very confused. I don't wan to go to a doctor unless it's serious.
What could this be or what's happening? Please any advice is appreciated.
