Confused! Help!

Elizabeth • I`m 23 I have one beautiful son Miguel and a sweet baby Lena. Married 6 years and done with having kids.
AF came on 2/14 and lasted 4 days I am now on cd7 and I had bloody cm today I'm pretty sure it's too early to be from ovulation but I'm not sure if I should extend my period for glow to be accurate. I have not yet taken an opk as it is only cd7 of 29. I will take one later today but I'm sure it will not be positive yet. I did have REALLY irregular periods while on bcp because my body didn't like it for some reason. I've always been regular while off of it. Any ideas as to what's going on? This shouldn't hurt my chances for this month should it?
