37 weeks migraines?

I'm just curious if anyone else is going thru this..I am 37 weeks and for the past week every couple days I've had migraines?..I get the auras and can't see right then bam the worst headache ever!last week when I mentioned it to my doctor I was told to drink a can of pop...but I'm not normally a pop drinker I do usually drink one coffee a day so it's Def not caffeine related!is anyone else getting migraines all of a sudden too?i can also add that I never usually get headaches of any kind.
