Unsure

Hi ladies,

I am currently trying to figure out what’s going on with my body. I’m 12 days late. Me and my ex had unprotected sex on October 13th that was cycle day 12. Today I’m in cycle day 49. I took one pregnancy test a week ago and it came up a faint positive. (I have a picture) I took one the next day around noon and it came out negative. I haven’t had any symptoms other then my back hurts, i have pelvic pain off and occasionally nausea, Ive been emotional but then again I’m always emotional. I have a doctors appointment next week. But I was wondering if this has happened to anyone and what the end results were?
