Anyone experience this?

I have two questions.. so

Can you ovulate the day after your period?

Can you get pregnant right before your period and still have your period?

So I was late.. I have been having normal periods since I had my son almost 8 months ago. I missed my period last month. I didn't have it until the beginning of this month.

I had sex 2 days before my period started. Today I had an unusual amount of clear stringy discharge with a little pink in it..

Yesterday was the end of my period it was light pink yesterday. It's all unusual? Anybody experience this..?
