Heavy feeling.

I’m having this strange pulling dull ache/pain where my womb is, It’s like I have a weight in my stomach!!

It started on my first day of ovulation. Ive never had it before, I’m 26 and have had periods since being 8years old. Has anyone experienced this before or know what it could be? The only way to stop it, is to lye in a Hot bath but as soon as I get out it’s back!
