I have low blood pressure anyway.. well did have all last year whilst undergoing arm, thigh, and 2 breast uplifts with implants! I fainted once before when I foolishly took a look whilst the surgeon was taking blood for testing.. and once again 2 days after surgery when I got out of bed for the first time. Today I was at the dentist for a routine checkup.. all ok.. except some touching up on a white filling needed to be done. Nothing major.. I am fine with dentists and the drilling etc. But the minute he put the cotton wool mini bolster thing into my gum to hold my lip out the way.. I started to feel queesy.. then thought.. AH!! this must be morning sickness and I am starting to experience it one late afternoon 26week gone nearly.. thought nothing of it. But 30 secs later the feeling got worse.. and the room started to go black. I said Stop.. feel like I am gonna go be sick.. oh and feel like I am gonna faint. WIth that.. I felt REALLY BAD.. my head was spinning and I felt so sick. I was heavy breathing almost panting as I went all sweaty and couldnt breathe! The dentist hollared something and all these people (3-4 in nursey uniforms) came rushing in through other doors I hadnt noticed were there before.. then my vision went black. Next thing I remember is dentist laying the back of my chair down.. and shouting at me to open my eyes.. whilst gently tapping my cheek. They gave me some water and made me up some more with glucose in it. After 3-4 mins I was coming round. The dentists nurse assistant said "oh thats better your face is going pink again cos you were a whitey grey before". I kept saying sorry.. I felt so embarrassed. What a scary feeling. Scarier than I have ever experienced before. I hate that.. is this cos your prone to low BP when your pregnant?
