I’m so confused

I have been trying to have a baby for 6 years with the same person! Yesterday I was supposed to start my period I went and had a Pap smear done then had brown discharge stuff on my panties and when I wipe I still haven’t had my normal bleeding the week before this I had vivid dreams like crazy dreams and they all appeared so clear I normally do not remember my dreams at all my boobs were really tender and hurting and I was an emotional mess which I know those things can be a sign of your period coming as well they done a pregnant test yesterday at the doctors it was negative but still I’m not having a regular bleeding period.. has anyone else experienced anything like this or can help me understand what’s going on? I’ve had a little cramping before the Pap smear but now I’m not cramping so I’m just all confused lol
