Bully button pain?

Pa

I’m on my second cycle of Letrozole. First cycle I had an early miscarriage. When I found out I was pregnant I was having what felt like scratches behind my belly button. But it’s been just over 2 weeks since and about to O again any day and my belly button still hurts a bit and the area below when I push it or even if I bend over. Anyone else experience this and found out what was going on?
