Using Crinone

Ok so, per instructed by my doctor, I’ve been injecting crinone vaginal gel once every morning, to help with the lining of my uterus. Because of this, and the fact that the gel doesn’t dissolve, I can’t tell if I’m spotting (I do clean out the area every couple of days, and it’s usually just whiteish color, but I often notice some dark brown clumps. Sorry for the imagery). I’m currently 5w3d, so I know spotting is normal. Anyone else using crinone have this issue? And were you ever able to confirm if it was spotting? Thanks everyone! After three years of trying and many rounds of IVF, I’m crazy grateful to be here!
