I'm 32 weeks pregnant and this last week or so I just feel constantly tired and especially noon-ish I need to put my head down on the sofa and sometimes drift off.
I always make sure the windows , gate etc is locked If I feel a bit woozy but I'm always aware of that when I have my toddler etc. but sometimes I like properly fall asleep which freaks me out as my toddler pokes me to wake me up or has to give me a shake! 
And sometimes having a cup of tea/coffee etc suddenly makes me much more tired.
I'm just a bit confused really and a bit worried
AIBU to be this sleepy at this point??
