Hi all!

I am 22 and have endometriosis. I have been TTC for 7 months now but I have noticed that my cycle has changed quite a bit and I am irregular (29-56 days) and my period is short (1-2 days medium bleeding and 1 day spotting) I am also bleeding dark burgundy-brown.. never pink or red. I have been tracking my ovulation with OPKs but have only ever gotten 1 positive! I meet with my dr at the end of the month but I was wondering if anyone had any insight.. I am worried I may have another issue that could be affecting my fertility.. comments are appreciated ❤️
