Pink creamy discharge and other weird symptoms?

6 months ago I got off birth control and haven't had a period since. The past couple days, I've just been feeling off - stuffy nose, itchy nipples, breasts sore on the sides, and cramping/twinges that almost feel like AF but not quite. On Tuesday I went to the bathroom and when I wiped, there was some creamy discharge that was so light pink, you almost couldn't tell. I had nothing the rest of the day, then yesterday more pink spotting, just a smidge darker and with 2 teeny tiny clots in them, they were literally like pinpricks. Today, no spotting in the AM, but just now went to the bathroom and more spotting, still very very light pink. CM is like a mix between creamy and EW. My period has ALWAYS started with some mild cramping and a bit of spotting the day before, and then the next day my normal flow will start, and the only symptoms I ever get are mild cramping here and there. I just pop my diva cup in and breeze through the next couple days. Now I am on day 3 of this light light spotting and different symptoms, and no idea what it could be. Other websites and forums suggest implantation bleeding - but it would still be too soon to test if that were the case. I plan to take a test Saturday, but this is all driving me bonkers. Has anyone experienced something similar to this? what was your outcome?
