I went off birth control 2 months ago. Immediately, the day after I had light spotting for two days. Then roughly 10 days later I got my normal period on the exact day I always have. I recently had sex, used a condom, but now am late for my period this month. I have taken 2 pregnancy tests, both say negative. Is it likely that it's pregnancy or just normal adjustment from getting off ***** control pill?
