So I m 21 years old. My periods have always been 6 to 7 days long. On January 15th I slept with someone without protection. On January 17th I had a period so I new I wasn t pregnant. Well after a week went by my body wasn t feeling the same, I was tired, bloated, cramps and just not feeling my self. That went on for three weeks.i did take four pregnancy test three came out negative and 1 had a faint line. But I wasn t sure if the faint line was there because I looked at it too late. Well then my period came late on February 16-17 it was heavy those two day then it just stopped. I ended up just spotting a pinkish color mixed with brown for just a day. Now I still feel bloated, small cramps mood swings and tiredness What s could be going on? I just know I m not pregnant. Because the test says it itself. Not taking any medication. I last took a pregnancy test earlier this afternoon
