Hello !

So I have been on the BC shot. The last time I received the shot was in early July. I have not taken it since then. Meaning I was scheduled to take it in October. So I have been off the shot for 2 and a half months. Last Thursday I started seeing a brownish creamy discharge (no odor) for 2 days. Yesterday I spotted red blood once all day. This morning it has changed back to the brown creamy color. I do have unprotected sex. Last Monday I did take a home pregnancy test. It was negative. I took another one yesterday. It was negative. Can you tell me what are my possibilities of what is going on with my body.
