Leakage

Kirsty
A bit of advice ladies. Im nearly 32 weeks. I was walking my eldest school this morning when I felt a wet treacle through my underwear. I could feel it through my leggings. Luckily his schools just down the road and I didn't need be in work until 11 so I went home and checked and there was a damp patch there it wasn't wee. I put on a panty liner and checked a hour later and there was dampness but not as much as before. I've been having period cramps for a week now and my midwife said it's normal. I haven't been able contact her today so thought I'd post here for some advice thanks in advance.
