Skipped a month, sex early June, still no AF

My last period was in April. I had previously been taking Progesterone, as I have PCOS and wasn’t having AF, but I’ve been off it for a while and had been regular since. I seemed to skip May, but early June (6) we had intercourse. I STILL have yet to get AF, and it is impossible to know what day dpo I am- but goodness.... do I want to be pregnant. I tested several times (first time had an evap 😡, but since all pink dye negs but I feel like it’s probably just too soon, as its only the 21st. I also almost always get AF on 20th, and have no signs. I keep thinking my breasts are tender, but not too the touch. Nipples are super sensitive however.

Any insight would be much appreciated.
