Late and BFN

 I had an irregular period before i was on the pill. I was on the pill for 7 years and recently got off in april and we have been TTC since. For the past few cycles since ive been off the pill i have had a cycle if 36 or 38 days. I am on CD 56 with no sign of AF. I took 3 hpt that all came back negative and i took a blood test that also came back negative. Recently started signs of a bladder infection but the urine test came negative. I feel like my lower belly is growing but it is probably my mind playing tricks on me. I dont know what to think anymore. Does anyone have any advice or thoughts?
