i am 13 days late for my period. i am never late. we have been ttc. HPT showa negative. i even had qualitative blood test on 7th day of my missed period but the result came back negative. my doctor has asked me to come back after 3 weeks. i would like to know if anyone has experienced negative blood test but turned out to be pregnant. i am also having some tingling sensation in my brests and they are itching. i also feel like AF will come any moment and keep on checking. also i had very light spotting for a few hours on 22nd day of my previous period which is something that has never happened to me before. i am 27 years old and this is the first time i am ttc. please reply me so that i can feel relieved. thanks a lot for reading.
