I need help!! 😬 I'm having weird symptoms at 19w4d.

Warning TMI. This is my second pregnancy and I'm only 19 weeks and sweating soooo much in the croch area. I am also having cramps and even sharp pains in my lower stomach and vagina. It's too early for BH right? And I don't remember my panties being so wet all the time with my first pregnancy, makes me think my amniotic fluid is slowly leaking or something! I'm I paranoid?!😳
