I’m probably paranoid

Samantha

So my bf and I started having sex, I started taking my birth control at the same time and I was reading about how it takes a week for your birth control to take the full effect. He has never finished in me, always pulled out. Well it’s been about two weeks and I’m probably just paranoid but I’ve been experiencing nausea and vomiting but could also blame that on my extreme migraines I have. I’m just paranoid because we both want a kid but it’s too soon in our relationship. Also for clarification I’m 21 and so is my bf so it’s not a teenage thing. Any advice or reassurance would be wonderful.
