I’m lost-please help

Today is CD 40-I’m a normal 28-30 day cycle...but have been ttc on/off for about 8yrs with endometriosis issues to add to the trouble and one ovary (had to have one removed because endo took it over). I have only had negative hpt including a first response today with fmu and a negative blood test on Tuesday. My OB didn’t give me any guidance besides my test being negative but I never skip periods or have cycles this long!! I’ve had symptoms but seem they could go either way (sore boobs, had 2 days of pink tinged cm(which I’ve never had), back pain, very minor cramping, bloating). This cycle just seems different but I’m going nuts here!!! What should I do?
