so I just have a question or 2 looking for some insight,

I had a miscarriage january17,2018 then had a chemical pregnancy the end of march. I've been trying the opk strips and can never get a positive read but I've had ewcm for the past 4 days. now I'm getting lots of odorless discharge that when it dries in my underwear it's like whitish pastel yellow. my period isn't expected til may 3rd. can anyone kind of help me understand what's going on? I feel so lost
