Question 😩

Layla💗

Hey guys.

I have a question, hoping someone could help and answer.

My Fiancé and I are trying to have a baby.

My ovulation day is January 11th (shown as below) We had sex (un protective) January 6th, 8th, 9th and 10th. On the 12th of January I had bad lower back pain and cramping but not bleeding or anything. BUT on the 13th I had period bleeding and till this day I still have it. I still have the cramping with isn’t that bad and lower back pain.

Anything that I should be worried about?

This never happened to me before so I have no idea what is going on.
