Hi everyone, my husband and I have been trying to get pregnant for three months now, and last month I had my period on Jan 11th, I haven't gotten period this month, I have been feeling cramps, lower backache, tender breast and nausa some times, but no sign of spotting, I took a HPT it was negative, and last week I took a urine test still negative, do you think I could be pregnant; my doctor advised for a blood test; if I am why it is not showing in the urine test? if I am not pregnant why Im not getting my preiod. thanks
