My last mensturation cycle started on jan 12, 2007 early morning 2 or 3 am. I always only bleed for 3 days, so I stopped bleeding on jan 15, 2007 but during this time me an my husband had unprotected sex and he ejaculated in me. Could pregancy result from having sex during this time?

Also, I have not been charting my cycles lately, but sure that they last for 30 days. We also had unprotected sex in which he ejaculated inside of me on jan 22nd, I dont know exactly when my ovulation occurs, so I dont know if I was fertile at this time. Could I be pregant from having sex at this time?

Another important factor is that I was on the deprovera shot for 5 years and never had a menstruation period during that time, other than about 4 times spottings. My last deprovera shot in march of 2006, and I was supposed to go back in june to get another one, but I want to have another child soon, so I decided not to. 2 weeks after my deprovera shot was due in june, I received my mensturation cycle, just as if I had never missed it. Since I was on the deprovera shot for so long, and have only been off for 8 months is it even a possibility that I could even get pregant anytime soon?
