My last period was 2 weeks ago, last week I had unprotected sex, the condom broke so I took a plan b. I had no side affects and I still haven't had any side affects, my next period doesn't start until another 3 weeks... I woke up this morning, wipes and saw pinkish blood everytime I wiped. Is this the plan b working?because it's definitely not my period and I definitely don't wanna say I could be pregnant.
