Hello Doctor, I am 32 years old and trying to get pregnant for quite sometime. I had my period on OCtober 25th. I saw the ovulation discharge on November 3rd and had sex that day with my husband. About a week and a half later I got some symptoms like wanting to use the toilet more than i usually do, some back pain and breast pain. However on November 22nd, I started to bleed but it was not like my usual menses. the blood flow was very scant compared to the normal flow that i would have with my menses and also dark brown blood, i bled irregularly for three days and on Nov 26th i took up a HPT test early morning with 1st urine sample. I got a pale line of T which disappeared almost immediately but got a dark line of C which stayed. ALso i have got some swelling in the coccyx region and the back pain still comes and goes. what does this mean, could i be pregnant?
