My last period started around June 7th and lasted about 5 days. I had unprotected sex with my boyfriend towards the very last day of my period where I still had some discharge. We had unprotected sex 3 times that day within about 3 hours and each time he pulled out. About 30-60 mins afterwards I took plan b and a couple of days later on fathers day experienced bleeding kind of like a period. However my period was supposed to start today (July 5th) and it is not here yet. Could I be pregnant? Ive been really sick lately. I also had unprotected sex like 5 days ago but he pulled off the condom and pulled out.
