Feeling "wet" down there... Is this normal??

Alexis • Expecting our sweet baby boy in April.💙 I thank God for giving me such a wonderful opportunity!
So.. this is TMI... but I feel really "wet" down there but when I feel around.. I feel nothing... it almost feels like I'm "wet" on the inside rather than it coming out. I'm 18 weeks pregnant and I'm just concerned and stressed about this pregnancy... I haven't been happy at all....
