Cramps

I’ve been having cramps off and on for a week now...

this app says I’m suppose to start my period in 5days

My flo app says I start in 3days

I took a pregnancy test yesterday and it said negative..

And the past few days I’ve come home from work and I’ve done nothing but sleep, my boobs don’t hurt super bad but they are a little sensitive but not so bad I can’t touch.

Also yesterday I had a small amount of clear jelly like discharge but haven’t had that again since. I’m so confused on what’s going on with me right now
