Early Ovulation!?!?!

Victoria • My partner and I have been TTC for many years with no luck. We`ve had 4 Miscarriages and 1 Ectopic pregnancy. It`s been a stuggle to get pregnant and stay pregnant.

Is it normal to have light spotting 3 days before my expected ovulation date?

Glow says I may ovulate July 29th but right now I am experiencing light pink & brown spotting with very mild cramps on the left side, however, I have little to no fertile CM. Maybe a very slight amout of watery CM with the light spotting is present.

Am I possibly ovulating early? If so, I am worried about the absence of fertile CM.

I have PreSeed but I feel that the spotting will reduce the effect of the PreSeed.

Any thoughts?
