Not pregnant and I’m currently on the implant. I had to take a plan b about 3 days after getting the implant because the 2nd day of having it, I decided it was fine to have unprotected sex. (Yes I know I’m stupid). I am sexually active so I always make sure to pee after sex but since the last time, I have no stinging pain when I pee so I don’t think it’s a UTI. I can go to the bathroom and about 30 minutes to an hour later, I have to pee again yet I don’t drink any liquids in that time span. Why is this happening? Is this from the implant or plan b?

(I got it recently about 3 weeks ago)
