I need help I might be pregnant

Okay this is going to be a long one to read but I need help please anyone. So I’m on the pill, and once I’m done with one pack I don’t take anything for a whole week so I can have my period. Well I was supposed to take my pill last Sunday the 5th of November. But I forgot because I got off work late and just took a shower and went to sleep. Just to put it out there I take my pill around 11 at night because if I take it any sooner I’ll be sick throughout the whole day. So I didn’t take it that Sunday but I took it the next day November the 6th at 11pm. But I had unprotected sex that Sunday the 5th and also that Monday the 6th is there any possible chance that I’m pregnant. Because I’m at work and I ate lunch here around 6pm and an hour later I was making food and the smell of it made me run to the bathroom and puke my brains out. I spotted once I don’t remember the date but it was sometime this week. My back is hurting, I’m having small cramps here and there but they’re not like period cramps they’re not as harsh. I’m nauseous, my boobs feel a little sore. I’m just scared what if I am. I mean I’m almost 20 I feel capable of having a child, it’s just I wasn’t planning on having a child so soon.
