Feeling confused

Danielle

Little back story… I should of gotten my period 5 days ago. I had a horrible cold that then turned into a horrible sinus infection and the antibiotics given were not touching this thing. Went to dr again and was giving stronger antibiotics, but realized I hadn’t gotten my period yet so I tested. The 4 tests I took definitely had faint lines. Went to ob to have blood test and I came back negative for pregnancy. I figured maybe it was too early and I’ll stick it out till I finish the first does of antibiotics I’m on, just incase I actually am pregnant. Spoke to my ob on Monday and said I’ve gotten another faint positive and asked to have blood and urine again bc I was still really not feeling well. Both came back negative. They told me to treat my sinus infection. Still my gut was telling me not to. I went and got a bunch of cheap tests and those came back negative, but just tested again with a better test and their definitely is a faint line. Has this happen to anyone? Could the blood test be wrong? Maybe it’s too early. If I am pregnant I’d be 5 weeks tomorrow. Pics below are of test I just took. K
