I am currently in the 7 month of my first pregnancy. I stopped smoking when I found out I was pregnant. However, by the 4th month, I was constantly fainting or feeling very dizzy. Nothing helped. I fainted pretty much everyday of the week up until the middle of my 6th month or so. I went to a nearby hospital where they kept me overnight. When I was first checked in, my blood pressure was 80 over 62 or something like that. When I was sleeping and my fiance was at my side, he said my blood pressure dropped to 62 over 45 and again lower to 58 over 32 I believe. (The numbers might not be accurate but I'm not a doctor.) They did tests on me and the baby. The baby was perfectly normal. I, on the other hand, was becoming very sickly from the dizziness and blackouts to not being able to keep food or liquids down. I blacked out twice in front of the doctors within an hour's time and the second time it happened, I couldn't recover from it and my blood pressure wouldn't bounce back. They kept me overnight for more testing. My fiance said I stopped breathing at one point that night and that my heart stopped. He woke up from the sound of the heart machine beeping, banged on my chest, and I started breathing again and my heart started up again. I went to a Cardiologist a few days later who had me hooked up to a haltar monitor for 48 hours. I'm still waiting on the results. Since I know smoking increases blood pressure I had one and it instantly made my dizziness go away. It's not from withdrawal because I've been on and off smoking for 3 years; I can go without a cigarette and cut cold turkey whenever I want to. Since I've been smoking, my blood pressure is now at 90 over 72ish when I go for my check-ups. I know smoking is bad during pregnancy, I'm completely against it. However, I feel like at this point smoking is better than the blackouts. Not only because I feel better, but because when I would get the blackouts, sometimes I would stop breathing entirely and my heartbeat would slow down significantly. The baby is very healthy and is growing better than expected, though. The doctors told me that the low blood pressure can permanently damage my vital organs and hurt the baby severely. I drink plenty of fluids too. I just began my 7th month, the baby has been kicking me since my 3rd month. I only have a little bit more to go and then it will be over and hopefully everything will go back to normal. Hope this helped. My doctors were pretty confused and still are.
