I’m 19 weeks with my 3rd baby

I did not have this problem at all with my other 2.

Well I lie... my first one towards the end maybe 37 weeks? I had sharp vaginal pain

Well I’ve been having it on and off all day today and it hurts so bad! I have to stop what I’m doing and kind of just clinch my legs together till it goes away

It’s like. Sharp stabbing pain in my vagina

My pee is clear so don’t believe it’s a uti ?

However I have been holding my 2yr old and 4yr old off and on today cause I had alot of errands to do and well when one takes off running of course im carrying them back to the basket or holding onto them to not run at all 🤦🏽‍♀️

Could that have something to do with it? I have also been getting cramps in my lower abdomen on and off and I figured that was from holding my kids and with them being 30lbs & 36lbs i figured they were to much weight on me

If it continues should I be worried and call the dr ?
