Very heavy watery discharge

Marissa

I’m 3.5 weeks pregnant and I woke up this morning to a puddle of wetness in my underwear. I thought I peed my pants but it was discharge. I’m having a little today but not like last night. I’ve been drinking a ton of water so maybe it has something to do with that? I’m having almost like ovulation cramps. Is this normal? Has this happened to anyone else?
