Has anyone else had problems with fainting during pregnancy?

I had chronic asthma as a kid, so I know when I am going to actually fall over, I know when I’m going to faint. It has improved and I was cleared.

I’m only 10w and I fainted once around 7 weeks.

Yesterday I was sitting here and got up to go get cereal, as I was pouring the milk.. I got really anxious and knew so I almost sat on the kitchen floor and instead, thought if I fall I will hit my head so I went up to my mothers room and sat on her bed and told her “I feel like I’m going to pass out” & next thing you know I sure enough fainted.

My mom called 911, they took me in said my blood pressure was low and did all kind of test. Also two ultrasounds; they worried more about baby. Everything with me is fine, even seen baby moving it’s hands and all.

I was wondering has anyone else had this issue and did it get better?
