I'm 21 and 15 weeks now, before I got pregnant, my BP was usually around 100-110 over 80s... but since I've been pregnant, its consistently in the 80s over the 50s (I bought a BP thing at CVS, so I take it a few times a day), and it makes me feel terrible... I'm tired, nauseous, and I have headaches. I'm not on any medication other than prenatal vitamins. My doctor doesn't seem concerned and says I should drink more water, but I've been trying to drink around 8 glasses a day, sometimes I only drink around 6, but I usually drink 8.
Has anyone else experienced this? Should I get a second opinion?
