Frequent urination, heartburn what gives?

Recently I have been feeling different. I've been having to go pee all the time like 7 or 8 times before noon, everytime I go anywhere I go before I leave then end up having to go when I get their too! And I have been having heartburn at odd hours like when I woke up at 7am and I had it bad! I was thinking maybe it is my impending period but my husband is worried that I may have diabetes I think I might be pregnant... what do you think, any opinions would be appreciated!
