FTM.... I need help

🖤🍔
I'm a FTM living in a different country then my family and don't really have friends or friends who had had babies... but I have a question or two.
1) Are BRaxton hicks painful? 
Every now and then I get this super painful period like cramp. It hurts and I have to sit down or lay down then it's gone after maybe 30 seconds- 1 minute. 
2) Does anyone else get these sharp pains in their vaginas? I know it sounds weird but I get these sharp lightning feeling pains in my vagina/pubic bone area. They come and go. 
I have my 32 week appointment on Tuesday, and will definitely ask my doctor. I was just wondering if anyone else has had these odd pains?
