implantation bleeding??

Hey everyone.. I am writing in here to get some opinions… I am a mom of 2 boys who are 6 and 9. I got my period on April 23rd ( a day early) and had MAJOR pms beforehand. The worst it’s been in a long time. I think I had a normal period as far as I could tell. My husband and I had sex on the 4th day of my period (when it was very light like we normally do) which was the 27th. We actually had sex twice which is not typical for us…anyway…On tues (May 2nd) i had pink discharge which continued until yesterday. It was very light, no actual blood…and my period was definitely over. I NEVER spot in between periods. The only time that has ever happened is when I was on birth control. (Which I am not currently on, and haven’t been since Feb of 05) Also today I have thick white discharge. Is is possible that I am pregnant? I’m confused because I just had my period and it seems that it isn’t possible…Could someone help?
