I have been having unprotected sex with my fiance' for the past month or so and he has finished in me as well. I thought I started my period but it was so light(a light red/pinkish color occasionally a brownish color) and only lasted a couple days when it always lasts 4-5 days. My cramps were even different. I usually cramp really bad the first day and thats it but this time my cramps were very mild but lasted like 3 days after I started bleeding. Also my appetite has increased.. I'm hungry like ask the time lately. And also been randomly light headed...I just have felt a little off lately if that makes sense....HELP
