HELP!!

My periods been late for now a month, all negative tests sadly. No sign of period what so ever. I stopped taking bc pill back in late June because my partner and I decided to start ttc. I have to say my diet isn’t the greatest but I am trying to get it back on track.

The night before I went to get a blood test for pregnancy I took an at home pee test and I swear there was a really faint line. The blood test was negative with my hcg being less than 2.

Can anyone like suggest things or like give me ideas on what could be going on?
