HI, I had sex unprotected my partner ejaculate inside & he continue to do whatever and ejaculate once more. Most people call it round 1 and round 2. However took the postinor 2 pill same day asap and the next within 12 hr, Took the first pill at 5: 54 pm and the next at 5: 54 am. Can I get pregnant? Because he did just come and pulled out he continued and ejaculate once more and I only too on dose of the pill. I want to know if I should've taken 2 dose? Now today November 7th 2018. I started to see light brown bleeding, light belly ache. I am wondering if I am pregnant and I am having implantation bleeding. My period normally looks bright red, but my period supposed to start from the 3rd of November.
