Help.

KC
I need help. I had unprotected sex 2 week ago then the day after I took a plan B, a day after i took the emergency pill i got on birth control (nexplanon) and i was supposed to get my period the 2 and i still haven't gotten my period. Is it normal because i got birth control or can i be pregnant because i remember the doctor telling me that the plan b is not 100% that i need to get a PT in 3 weeks?
