So this morning I woke up and between my legs was wet but I thought it was just sweat several hours later I felt my pants slightly wet I changed them and went on with my day now I went to use the bathroom and when I sat down I felt a trickle I wiped before going to the bathroom and it was a watery light brown discharge I’ve also been experiencing light period like cramps this is baby #2 but never had this happen before... any advice?
