Spoting a week after AF

Lalalala • blah

Average p. 7 days. Average cycle 36 days. Unprotected sex every 3 days. Last p. Oct 9th. Spotted for two days after my p. Stopped. Then spotted for two now days a week later. Stronger odor than normal, but not foul.

No cramps, no sore breasts. No symptoms of AF yet ( probably not due for a while since I run on 36 day cycle)

I did lose weight fast in the last 2 months, and I am on legally prescribed pain medication.

Just want an opinion. .before I belive Web MD about having all kinds of stuff..like cancer (they say that spoting a week after your period ends is NOT normal, and it can be an infection, or..or..or.. lastly..cancer. .

Ps- I am trying to convince, hence having unprotected sex every 3 days.
