On October 1st I stopped taking my birth control pills mid pack because my husband and I want to TTC. October 2nd I bleed for about a week. It's now November 11th and I haven't gotten my period. Around the time my period was suppose to occur I began to cramp really bad on and off but no period. During that week I was very tired. I took a pregnancy test and it was negative. Is there a possibility that I could be pregnant?
