Okay so I am sexually active and don't use protection with my husband. Around the time my period was supposed to start when I went to the bathroom after I peed I had light pink there for a good day and then it went to like a regular period had not severe cramps but enough to where I had to take some medicine. My period was weird and last 2-3 days and now when I wipe there's like brown discharge like stuff. This has never happened with my period and they're always 5-7 days. My breasts have gotten fuller and my acne has increased and some blue veins on my chest and restlessness. Any ideas?
