Rushed to the hospital

While I was at work yesterday I was outside for maybe 5 min and I don't remember it I blacked out but I passed out and apparently hit my head,back, and tailbone really hard on the concrete. I just remember waking up with paramedics surrounding me. They rushed me to the hospital by ambulance and hooked me to a bunch of heart monitors. I was fine and then they checked on baby. Baby is perfectly fine and healthy and has a strong heartbeat. They said that my blood pressure spiked which caused me to pass out. They said that since I have been in the hospital 3 times already for this kind of thing and severe dehydration and etc... I'm in for a long rough pregnancy. Thankfully my fiancé and mom met me at the hospital and were able to take care of me :)
