Cautiously hopeful

I have PCOS and missed my period at the beginning of August. ( I have been working hard on my diet and have been regular for over 6 months!) But I had a UTI right after my July cycle. We took 2 pregnancy tests last week and got positive results. I’m scared it’s just in my head and false positive results from the UTI or antibiotics. I have a dr appointment in a week and am so anxious to find out for sure! I’ve had cramps and sore breasts but again, worried it’s just in my head.
