Sorry to hear your news Cab.
I've posted a query about low blood presure on the preganancy board but I haven't had much info yet, I remember that Cab and Logic both had low blood pressure, I don't know if either of you can offer any advice.
I'm 16 weeks pregnant and have had fairly low blood pressure, latest reading was 90/50. I've had the odd dizzy spell so I've been trying to have lots of snacks, drink, stand up slowly etc and it hasn't been too bad until yesterday. I was at a work Christmas lunch and I'd just finished a large christmas dinner, when I started feeling faint, I went into the loo to splash cold water over me, but still felt really bad, collapsed on the toilet floor, and the dizziness stayed for ages, about 10mins, didn't quite pass out as I raised my legs up, but I took a long time to feel better and I then developed a headache which stayed for the rest of the day (unusual as I rarely get headaches). A colleague who used to be a nurse came looking for me, and took me outside when I was feeling a bit better to cool off - I was very warm, She's said that it will probably get worse during my pregnancy and I may need to stop work early. I've read about dizziness due to standing up quickly and not eating enough, but i'd just eaten - after snacking all morning and hadn't moved from sitting for about an hour. I do wonder if I may have overheated as I'd been working outside in the cold all morning and the pub was quite warm. But any advice on how to prevent this, if it is down to low blood pressure and if its likley to get worse would be really useful. Sorry to rant on. I would ring my midwife but she's on holiday.
