Just entering 3rd trimester and waking up every hour at night?

atoeller

I am 28 weeks (barely in my 3rd trimester) and was sick for about a week over all.  I was only sick because I was slightly dehydrated and had to get fluids at the E.R.  I was working on just sleeping while being home all week from work and was getting a couple hours in here and there at night.  Ever since I've been better this weekend (and end of the week) I have yet to get a complete night sleep.  I went to bed around midnight (for example) and woke up at 3 am, 5 am, 6 am, 7 am, 8 am, and then every half an hour after that (I assume it's because the sun is up and bright).  Either way, I am getting no sleep what-so-ever and don't know if it's because the baby is supposedly starting a sleeping schedule now or what, but I need to figure this out!
Should I call the doctor or what?
