I had an iud. I had it taken out about 4 months ago and then went on the pill. However the 1st month of taking the pill I ended up only taking 15 of the 28 pills. My husband and I decided to go off the birth control. I had a period on July 1, 2009 and then again on July 26th. We had a lot of intercourse during this time. We had intercourse the day my period ended which was July 29th. Now it is Aug 5th and I have light pink and brownish spotting along with some mild cramping. It doesn't feel like period cramps though. The spotting is not even enough to use a pad or panty liner. Could I be pregnant?

Of course you could. Any sex can result in pregnancy. I wouldn't say the chances are great, but certainly in the realm of possibility.

Best to speak with your OB/GYN. Only he can tell you for sure.
