Chances of pregnancy?

Sooo I’m 6 months postpartum. I had a period in February, April, and may. According to clue, I am 8 days late, however given that I’m within the first year of being postpartum that can of course be irregular. I took a couple of pregnancy tests last week, which were negative. My husband and I had sex tonight and then after I took a pregnancy test (not because I thought I was immediately pregnant - duh) I just happened to think about doing the test after. I did two pregmate tests which indicated pregnant. I googled if sperm contaminated urine could cause false positive and it can. I wiped with a wet wipe twice and did early detection test (says pregnant). I took a shower and cleaned super well - took another pregmate and shows pregnant. I plan to do another early detection test tomorrow morning. WHAT ARE YOUR THOUGHTS?!
