I fainted while 13 weeks pregnant!

I'm currently 13week1day pregnant and my body is changing on me very quickly! While being at work today I could feel that something was a bit different about my body. Shortly after being at work I realized my body was starting to feel hot and suddenly feel nauseated, I quickly than ran for a cup of water. After doing so I felt the same way and my vision started to get blurry! Next thing I notice people  surrounded around me asking " are you ok ?? " !! I couldn't believe it ! I quickly when to the doctor to check if the baby was ok and lucky the baby's heart was going at 155 !! Thank God I'm ok !! 💜💜
