I know exactly how you feel...I am 33 weeks and have been to the dentist 3 times this pregnancy (including yesterday) and have had 3 teeth pulled (2@once)...tooth aches are no joke and to me are just as bad as labor pains... But for some reason they get worse while pregnant due to the hormones I would guess... Which is why it is recommended to take good care of teeth before and while pregnant. I would suggest yu get clearance from yur o/b and have it looked at... Then again being that you are so close to term they may want yu to wait until after birth. Mine started at 10 else... I truly empathize and sympathize with yu dear.
