I had sex on monday, and on Wednesday till friday (today) I'm having a brownish almost black discharge. It's not much, but never pink or red. He used the pull out method with me and I know I had nothing inside me and his track was clear. My period is the most irregular thing on the history of the world, which is normal because I never was regular before. Help! Am I pregnant? I will be safe next time. I just wonder if I can be pregnant from monday.
