I missed one pill on Wednesday the 6th of this month. I took 2 pills on Thursday the 7th and had the nexplanon put in on the same Thursday. I have been on track for the rest of the time. I though had unprotected sex on Sunday the 10th. I freaked out and took the morning after pill on Monday the 11th. What are my chances of being pregnant? I feel weird or maybe I am making a mountain out of a molehill. Weird meaning I feel sick and bloated, tired and everything else.
