So we've only been TTC for a couple months and last month I got a serum progesterone test done on my 23rd day of cycle and showed that I ovulated. So we have a digital fertility monitor and I'm on like the 19th day of my cycle and I have been in "high fertility" for a week now, but it hasn't showed my "peak ovulation" yet. What the heck is going on? I've also had a UTI from hell which I'm taking an antibiotic for, but the dr said I should still ovulate like normal....it may delay ovulation, but not stop it completely. Any ideas for what's going on?
