I am a bit confused on what my body is doing. Last normal period was 12/7/14 lasted 5 days. Had unprotected sex (pull out method) 3 times since then. December 26, 28, and 31st. I was expecting my period to come January 11th and nothing.. I have been feeling slight cramps and sore breasts. Finally got what I thought was my period Sunday 1/11/15 after i took a pregnancy test which was negative. I bleed a little all day which I didn't think any different of it because that how mine usually starts. Easy flow then gets heavier well thought the day it didn't and this morning and all day today I've just been spotting here and there. It's bright red! But thought it was weird because I heard implantation bleeding should show up before your period not after your expected period. So I am a bit confused. I was pretty sure I was possible pregnant and took 3 pregnancy test before I got this spotting and all came out negative. So I am wondering what could this be? Could I still be possibly pregnant? Or is it something else? I had a miscarriage last may but since then my period have been good. By good I mean lasting me 4-5 days and getting them every month except November but I was going through some stuff so I think I didn't get it that month due to stress. But now i dont know what this could be. I'm tired, hungry, very sensitive.. lol Can anyone help?
