Hello. I am 20 years old and married. Me and my husband had sex when I was ovulating. He didn't ejaculate in me. 1 day before I was supposed to start my period I had light pink and brown discharge. Then later on, it changed to bright red. Almost as if it was a bright pink. Sometimes when I would wipe it would just be a light pink. My periods are regular, heavy flow, along with breasts tendorness and cramps. I didn't have any of the symptoms of my period. I bled really really light for about 4 1/2 days. Normally my period is from 6-7 days. This morning (2 days after I had stopped bleeding) I had dark brown discharge. It changed to light brown around an hour later. It doesn't have a fowl smell, my vagina doesn't itch or burn. Can anyone tell me what could be going on? Any information would be greatly appreciated. Thank you
