Fertility drugs and spotting

Bails
Okay I have a question, I am new to this. I started taking fertile cm and Myo-Inositol and I just had my period about 2 weeks ago. My SO and I had sex a few times during my fertile period and today is the day I am ovulating. I woke up this morning and I was bleeding but it was light and only seen as I wiped. The blood was actually like a pink color and continued throughout the morning and got a little more the later in the morning it got and then stopped. Is this normal, could it be a side effect of what I started taking? Or could it actually mean something more exciting? (it hasn't even been in my system a full day as I started taking it last night). Anyone have any helpful insight into this?! Also this spotting is not characteristic for me and my cycle. I read that some women do but I never have. Helppppp meeee 😊
