Hello. My implant birth control expired on 5/11. I had unprotected sex yesterday (6/13), and I am scheduled for my removal and new implant in 2 weeks (earliest they could get me in). I have had regular periods the entire 3 years (I was on depo for 10 yrs prior with no periods). I am overweight (200lbs, 5 7 ). I do get whitish discharge and increased sex drive like ovulation half way between periods, and I have since I switched from depo to the implant. This ovulation happened last week and the increase discharged ended 3-4 days prior to unprotected sex. Should I take emergency contraception? Will it work even though I ve already ovulated? Does it have increase side effects with already having an implant? Also, I cannot take estrogen, only progestin, as there is a history of the pill related stroke in my family. Help!
