I've been on birth control since I was 15 I am now 24. My boyfriend and I are wanting to try and get pregnant. I recently stoped taking my birth control the 3rd week of my pills. I believe I only took three pills that week. I am now 3 days late on my period, which I'm never late. Could I be pregnant? Or is it to soon to tell? I have no signs of a period. I took a pregnany test day one of missed period and it was negative. But I didn't think just not taking 3 pills would have my period all of wack.
