Birth control

So I started having sex about 2 weeks ago and sometimes we'd start without a condom but we would never let it get to that point where he came without one. Anyway, I went to get the implant and they told me I could because there might be a possibility of me being pregnant so they gave me birth control pills. Do they make you feel like throwing up? I've been feel sick since last night and felt nauseous for a while. And now that I've fully woken up I feel like throwing up. Can you get this sort of side effect so early? It's only my first time taking it. 😕
