Have a suspicion I might be pregnant again

I’m scared and looking for advice. I’ve been feeling sick lately and having cramps not on my period which were the symptoms I had with my first baby. My daughter is only 9 months old and I’m freaking out that I’m pregnant. My periods not for another 2 weeks so I can’t test yet but I just have this weird feeling. I just haven’t felt like myself.

Yes we had unprotected sex and my husband doesn’t let himself finish inside me but I know you can pregnant from precum and I don’t take birth control because it gives me horrible migraines. And we’ve been really stupid and not used condoms.

Guess I’m just venting lol. Anyone else have kids this close in age? I definitely don’t feel ready for another baby at all.
