Cramps,tingles..

Kristi • 22, married and expecting first🙌🙋👪
Past week I've been getting small cramps at the lowest part of my belly, and every now and then I get what feels like is tingles, or cramps in my vagina, they arent sharp but they are constant..I'm 13weeks with my first, so I know the baby isn't coming soon, but it is starting to worry me . anyone know what's going on?
