Confused

Desire
So i have had pcos and dealing with that alone is depressing but when i set up a fertility appointment they called and canceled it the day before :( anyways on to my confusion i had a natural period for the first time last month on the 19 of jan and now im having pinkish off and o. Spotting i dont even know if ive ovulated... However my breasts hurt if i turn on my left side i get nauseous. I dont know if the pinkish spotting is implantation or not because like i said not sure if ive ovulated but im not supposed to start till 5 days from now based on last months surprise period. Any ideas?
