I got married in Nov 2004 and had irregular periods before marriage.After marriage in convieced immediately in Feb 2005 unfortuantely had to terminate the baby due to acarnia(brain and neck not formed) in the 5th month(July 30th)and then the dr scanned and told that no PCOD and from July 30th i had regular periods.We got all the tests done and everything was normal except the karotype result which showed translocation of (8,18) in me and normal in my husband.But me and my siblings are all very very normal and no major abnormalities.The genitic dr mentioned that I have only 50% chances of a healthy pregnancy.We used to have sex but never took risk as we wanted to give a gap to recover.We never used any condoms or pills it was calculated sex.My last menstrual period(LMP) was Dec7th 2005 and my dr asked us to have sex on 13th,15th and 17th day and we did so and I have not got my periods till date.I tried 4htp and all came out -ve and blood test shwd hcg<2.However i feel some symptoms like cramps in lower abdominal,back ache,freq urination and bloating tummy.I visited the dr and she asked me to take a htp on 20th if -ve then start rogestrone tablets for 5days.Please please let me know if the test can be -ve still could be pregnant.If not what these tablets are for.
