24 weeks pregnant. bp is normal or sometimes on the low side. always wake up with a headache on the left side. normal?

Not unusual: Being pregnant is an abnormal state! Everything about it is different then the rest of your life. Not only that but things are constantly changing and your body is having to always adapt. Sleeping patterns and position, hormones, stress, weight, etc. check what has changed in the position of your sleep, have you started snoring? Discuss it with your OB. Happy Mother's Day
