LMP September 14th. Had unprotected sex with partner on the night of the 22nd, on the night of the 23rd, I got horrible pain on my breasts as if they were punching bags, my hips seemed to be stretching, cramping, constipated, headaches, nausea got blood tinged vaginal mucus VERY scant. On the 24th got beige mucus. Also got pale brown discharge. On the 25th got brown tinged mucus. On the 26th got sticky mucus. Today the 28th again a brown tinged, but very scant and sore breasts and cramping on right side, feels warmth around abdominal/pelvic area and a little around face and neck. Negtive for UTI, NO burning, NO itching. Same partner since March. What could this be related to? Possible conception? Thank you!
