Ovulation Bleeding

So today I am on my 5th day of Ovulation and I've been having period like bleeding and even had a clot. I was taking Ortho Tri Cyclen Lo for around 6 months and stopped over a month ago and had my first period as normal and everything was going as usual until I started bleeding. I have had sex but we use condoms and withdrawal as well I don't have any other symptoms except for a little weakness but I'm also anemic so blood loss usually results in weakness. I'm just a little confused and wanna know if this is normal. I read that it might be due to low estrogen levels or it's just a sign of healthy ovulation. I've never had this happen before so I'm a little worried.
