Okay should I go to the hospital?? My heart randomly starts racing while I'm sitting down. I get light headed and it takes my breath it's like a flutter between my lungs. I got hot earlier when It happened like my blood pressure just got high. It doesn't happen all the time but it's been happening the past few months I'm almost 31 weeks pregnant. I did tell my obgyn but she didnt listen to me or my heart she said it's normal.. I'm concerned about it effecting labor or the baby at anytime. Any one ever experience this? What you think it is? I haven't had caffeine, I'm not really stressed or anxious, I'm not dehydrated, I ate and I haven't had a lot of salt. I don't know what's causing it.. it's happened 6 times in the passed hour and a half. The last time is when I got hot and started sweating some I think my blood pressure got high
