leaked clear liquid last night?

so i'm only 19 weeks and 5 days pregnant but last night i leaked clear liquid. enough liquid to get my underwear wet but not enough to soak the bed. i smelled it (i know gross🤢) and there's no smell to it whatsoever. i thought it was discharge at first but it's not sticky or slimy or anything like my normal pregnancy discharge. this weekend and yesterday i had cramps that lasted at least a min and went on for 10 mins. but i haven't had any this morning. ive been pregnant before but this never happened with my first. help!
