Question ladies

The other day I was at the store with my daughter, at the time I was 22 weeks pregnant. Anyways, we were walking around getting groceries and all of a sudden I felt the blood drain from my face, my face and hands got clammy, I felt like my breathing was labored, I couldn’t see anything, and everything sounded really far away. I squatted down by the cart and after about 5 minutes I started to feel better, just really weak, so I finished shopping and we left. On the drive home, literally 3 minutes from the store, I had to pull over and throw up. I’ve had this happen a couple of times and haven’t been back to the doctor yet, I go tomorrow so I’ll tell her about it then, but has anyone else experienced this??

Yes, I had eaten before we went to the store lol
