I’m dumbb

I’ve been on the implant for 8 months now and me and my bf had sex about a week ago and he came in me and since 2 days ago ive been feeling like throwing up. I’ve been feel like that a couple weeks ago but didn’t have sex but since I’m starting to feel like that since i had sex I’m just paranoid and dont know if this is symptoms from my implant. I don’t know if I’m prego or not.
