Hello me and my husband are trying to get pregnant. Every year magicly I ovulate by my self the month of September we did something everyday tree times a day. I started out with pinkish discharge four two days then it stop after I just started bleeding but it wasn't like my normal period it was dark red then brown and pink. I stopped bleeding after two days but I still have some cramping, pain in my cervix area, back pain, my boob and nipples are sore. Its been six days since I stopped bleeding I don't know if I'm pregnant are not I took a pregnancy test the day after the bleeding stop and got a BFN. I might have taking it to early I don't know can someone give me so insight??
