Labetalol for BP and headaches

Since I was 4 weeks pregnant my dr. switched my BP med to Labetalol. Since then I have had horrible migraines all day, dizziness, cloudy vision and nausea. Some of the nausea was from the baby too. I'm now 10 weeks pregnant and couldn't take the migraines anymore. I was so dizzy yesterday I couldn't walk without wanting to pass out. I figured out it has to be the pills. I stopped taking them and so far today I feel great! So I'll have my dr. switch my BP med on Monday. I just wanted to let you mommies know what it could be just in case you've been having the same symptoms on this med.
