Pressure in lower stomach/uterus area.

Hi everyone!
I have a quick question.
Early to day I had a sharp pain in my uterus area. It's coughs me by surprise, I actually yelled.. But later on in the night I started have some pressure on my uterus.. I've never had this before! I was sitting in the chair and the pressure was making it hard to take a deep breath.. I've never felt this before.. It even feels uncomfortable to lay on my stomach.

We are trying to get pregnant but I don't know if it could be that..
I had my period on the 7th and ended on the 12th
I was supposed to be ovulating from the 16th to the 22nd (according to an app on my phone) we did have sex every day during that time..

Could the pressure have anything to do with conceiving or anything? I didn't think it could happen that fast. My next period isn't due till the 4th of February so testing might no be possible.

Thanks for all your help!!

I've had pressure in those areas and I am pregnant but mine isn't like breath taking pain some pregnant women are different I've had doctors tell me it's normal to feel pressure in those areas when pregnant because your baby is pressing on your bladder and your uterus is expanding depending on how far along you are but just take a test or ten lol to find out if your pregnant or just wait until AF is due again then test
