Help!

Back in September I tested positive pretty early they were faint but there I end up getting a UTI. It was pretty bad I start having some bleeding. I asked dr & said it was normal but since I wasn’t able to get in with them they said I can go to the ER (I decided not to go, because if I was having a miscarriage, it was nothing they can do and that’s just another bill) due to previous experience with a miscarriage. After the bleeding stopped I took a test it was neg, so I just left it alone obviously because it was so early fast forward now still no period (super late) And now boobs & nipple are sensitive (haven’t experience this years) if I’m still pregnant I would be 9 weeks. Yes I know I should go to the doctor not appts available anytime soon. but I want to know if anyone has ever experience something like that? I will test if still no cycle by Friday. (No sex since September) Would you think the antibiotics would cause a negative since it’s flushing out the urinary? I read no but still not sure. Just want to hear any experience
