What is going on? Late BFP?

Okay I recon I’m going around the twist. I have PCOS but have had regular cycles of 32-34 days for the last year and a half. I’m currently cd 48. I’ve had cramping intermittently since a few days past ovulation and a few days where my breast and nipples were so sensitive even the wind would hurt them. I have taken about 20 FRER since the day AF was due and almost every single one has come back with the faintest of faint line ( in the 5 min read time) but I’ve disregarded because they are known to get evaps right? Idk? I’ve been TTC for 4 years. These symptoms are new and I don’t feel like I’ve been symptom spotting.

Blood test came back negative. Docs told me to wait a week then retest. Now I’m going insane because I feel emotionally constipated.

Please send hopeful stories or late BFP!!
