Hello ladies Im 15 weeks pregnant and yesterday I started to get a really bad headache, followed by extreme thirst. When I say extreme, I mean NOTHING can quench it. I mustve drunk 9 pints of water today and still very very thirsty. I know normal pregnancy fatigue, but this is " I had to sleep from 11am-6pm today" type of fatigue with constant headache. This is baby number 3 for me, previous pregnancies both very healthy and straight forward. Im 31 and healthy weight (9.5st at booking apt and only gained 2lb or so since) Can it be gestational diabetes? has anyone with a healthy pregnancy had these symptoms as their typical pregnancy symptoms? I just want to know if this is within a "normal" range of pregnancy symptoms experienced by some women?
