TTC and I'm so confused

So without an entire back story, I have a pituitary gland tumor. I've been on my medication constantly for 3 Month and my period has been regular for two months.

We are TTC and I've been tracking my cm. It has changed in these last week's. It's been creamy white but not sticky for two weeks straight and more than I've ever seen (no crazy smell or anything btw). My cervix has been all over the place lol. I also have been very fatigued, nauseated and hungry lol Anyways my period is supposed to start, according to both apps I use, in 3 days. I'm so tempted to take a test but I've had so many negatives that I'm not ready for another one. I'm trying to wait to see if I get my period.

What do you guys think?

Pregnant or not?

Should I just wait?
