No AF!!! :( :( :(

ZT

Guys, I assumed I ovulated on the CD 19th/20th. I had sharp ovary pain and been taking temps. I had some light brown discharge CD 23 and 24. However I am on CD 37 now with no sign of AF. My last test was on CD 34 which was a bfn. My legs are super achy and stomach super bloated! I am so confused. I had a chemical 4 months ago but have had normal cycles after it. Please helppp :(
