Missed BC pills

Kasey
Last week, I went on a trip and forgot my birth control at home. I missed 4 pills. I took two pills a day for three days to catch up. Probably not the best thing, but I did it. On the third day that I missed a pill, I start my period. I wasn't supposed to start until this coming Tuesday. (I missed Thursday-Sunday) everything has been good and fine since then. This morning, I woke up with slight spotting. I wiped and that's it. I haven't seen anything since. I have been intimate with my husband several times. Is it possible for me to be pregnant? Should I finish my birth control pack I have now? Any advice is appreciated.
