Sept 7th

I'm 20 dh is 23 we have been ttc for 10 months now for #1 this is my first cycle on clomid. My cycles have always been 28 days but I'm unsure how long this cycle will be bc in march I had a miscarriage at 6 weeks due to under active thyroid ( I didn't know when I was ttc the first time and my levels are normal now ) and this is my first cycle after. I'm expecting af sometime arround sept 7, I don't temp bc I'm not exactly sure how to chart I didn't use opks this month because I go Saturday to get progesterone checked, I track cm and position and I'm pretty sure I od on the 23rd.
