TMI ...symptoms??

For the past week or so I’ve been nauseous and cramping throughout the day, I am constipated, I have a headache...and my poop is green?? I had the implanon for almost 4 years, taken out August 5th and had withdrawal bleeding from the 8-12th. I know that’s not a “real period” but I’ve been SO irregular that it’s hard for me to know what was supposed to be the new regular, and know it can vary from woman to woman. Because I had WANTED some normalcy I actually immediately started a microgestin pill same day I had withdrawal bleeding....having been so bad at remembering and the transitions in my life moving etc I only managed to take it for about 2.5 weeks. Since the end of August I haven’t taken any birth control and still haven’t had a period since the withdrawal time. On glow I am what would seem to be almost 30 days late from the pre implanon period but it’s really too tough to understand. I’m curious if these are pregnancy symptoms? Anyone else get pregnant shortly after implanon/body control pill stopping? Are these PMS/pre period feels? Hormones just outta wack?

I’m new to CP and CM but I’m having a high , semi soft cervical position and the last few days a very very lotiony White cervical mucus . Last hpt was on the 14th and negative with clear blue.
