Can you ovulate while on your period?

Whitney

I have always been very irregular, having my periods a month apart to as far as months apart. They are also a few days long to over a month long. I have been doing op tests and the clear blue monitor. In the middle of my period (it has been 3 weeks and 4 days so far of bleeding) the clear blue monitor said I had a high chance for 5 days followed by 2 peak days, on the two peak days I also had a couple dollar store opk say I was ovulating.

What are the chances of ovulating during your period?

Do you have a less likely chance of getting pregnant? Can the blood push the sperm out when you are bleeding?
