Clomid users? Tell me your experience with all your tests PLEASE!!?

OK, so here is my story. Endo for 4yr, no regAF, diagnosed with PCOS in May. Started 1st rndof clomid at 50mg in April and took a prog level at CD21 it came back at a 1. Started to take my 2nd round of clomid but they saw a cyst so we waited another 2 weeks. I started my 3rd round at 100mg and had my progesterone level done on CD 21, it was a 46!So, I ovulated and was hoping for a BFP but it did no. I started what I thought was my period, but it lasted only 48hours. Which was weird but my period did start on its own compared to the last 2 times on clomid. But only 48 hours...then I started clomid. Anyone have this on clomid? Short AF or short period & then preg?

I am now on my 3rd day of my third round. Hoping for the best! i am also using preseed, drinking fertiltea, and fertilaid. I have even thought about trying the robitussin after I stop clomid. I have also been tracking my BBT. I just wanted to share my story and see if there were any similar out there!
