I was spotting light pink and brown for 3 days but I could only see it when I wiped myself (from june 20 to 22). Then I was fatigued, light cramps, bloated, thirsty, urinating a lot, backache and a severe headache. All those symptoms lasted a week. I was to have my period on the 25th of june but still don t have it. I took three pregnancy test and all negatives. Can I still be pregnant?
