I had been put on azuerette birth control and I had been about exactly 1 week into taking it and I had unprotected sex the 1 week mark.. the same week I had missed 3 days worth on accident and started a period for about 6 days and then stopped. I stopped taking the pills then started another period that had only lasted about 4 days but it was a lot lighter than usual... I still haven't taken anymore birth control pills and still haven't gotten another period since. All I've had is frequent light pink spotting.. I had unprotected sex once again this past Sunday and that same day there was light pink spotting along. ever since the 3- 4 weeks ago of sex ive been extremely tired and having no apetite to eat normally.. may I be pregnant?
