I'm 17 weeks pregnant and I've had several fainting episodes. They're happening more frequently now too. One I fell backwards and gave myself a concussion after I hit my head on the kitchen floor. another time I passed out while reversing and hit a hedge. Has anyone else experienced this throughout pregnancy? I'm getting tired of having to take time off work and my midwife wants me to be signed off until they find the cause. I'm just wondering if anyone else has had this happen?
