hi I am 21 yrs old me and my bf have been trying to get pregnant I was supposed to start on the 9th of January I woke up had light pink blood in my underwear I assumed my period had came, so I put a tampon in and I went to change it only to notice no blood I woke up the next morning same thing no blood after my first morning pee. it happened three days in a row and now it is the 14 and I haven t bled for 3 days. I ve been tired, nautious, lower back pain , and a creamy like discharge . I took an at home pregnancy test on the 13th it read negative. what s going on? did I take it to soon? or could it be something worse? please help!!
