So I've called my obgyn about this and I'm waiting for a call back but I was feeling extremely nauseous at work. I took zofran the kind that desolves on your tongue and I couldn't keep it down. It got to the point where I had nothing on my stomach from throwing up and I just dry heaved. So I left work due to not being able to stop and I was driving home I blacked out hit a curb and came to probably a few seconds later. I was only a minute away from my house so I sat there for 5 mins to make sure I was ok and i was able to get home. I'm wondering if it was the zofran or something else could be wrong with me or if I just threw up so much I passed out. Has anyone else had this happen to them? I know my baby is ok I have a Doppler at home and I've heard the heart beat. I'm just concerned.
