Ovulation bleeding can't be heavy, right?

I'm preparing for the baby, but it's not going as well as I thoughtㅠㅠ

I'm curious about ovulation bleeding.

I started bleeding earlier than the expected day, so I was slightly hopeful it was ovulation bleeding, but after a day, the amount increasedㅠ

I found out that ovulation bleeding is usually just enough to stain underwear. If there's a lot, is it menstruation?ㅠㅠㅠsigh
