This is going to sound crazy..

So for the last two years my teeth have been unbearably sensitive to sweets. I was never able to eat candy, cookies with chocolate chips in them, or literally anything sweet at all. I would sometimes risk it by letting it melt in my mouth, but sometimes it would touch my teeth and id want to cry from the pain. The other day that happened..but there was no pain! Whatsoever! I just ate a chocolate bar and it didnt evem hurt a little! Does thus have to do with being pregnant? Cause nothing else makes sense
