Really Worried about what's happening

Ok, so about 4 weeks ago I went into hospital for 7 days and didn't take my pill while I was in. the night I got out I had a pill, and the next night. I started taking it regularly again, but two days after the 7 day gap I had sex. I'm just now starting to feel bloated with slight cramping and increased appetite and my period is 6 days late. And my anxiety has gone through the roof and I don't know what to do. I've kept taking my pills, and been having sex most days since this gap in my pills that I think put me at risk. I'm on new medication and I'm worried that may have an effect on the way the pills work as well. I'm going to buy a couple of testing kits in a bit and get a gps appointment no matter what the results show because I want to get off the pill I'm on and try another different one.
