PCOS and TTC

Br
I have PCOS and have been TTC for 3 years now..just started my second try on clomid..so far I my levels are at a 37 and im now a week late..last week my pregnancy test came back negative and also had a blood test done too which was also negative..my doctor wants me to wait for another week before testing again..has this happened to anyone else? Or am I literally just weird?
