Running during pregnancy

Hi everyone! This question is for the runners in this group!!! πŸƒπŸ»β€β™€οΈ

It’s my first pregnancy and I’m 10 weeks 2 days now..

Im a very active woman.. and I ran almost everyday before I got pregnant. 7-10km

From week 5-9 my breasts were hurting so much I just wasn’t able to run a lot because of the pain.

Last weekend I ran 10km and then felt pressure in my pelvis. My breasts stoped hurting this week..

My question is .. is it safe to run during pregnancy? When to stop?

Thank you so much!!!
