Hi, thanks for using healthcare magicPregnancy
tests look for the HCG hormone. Urine tests can normally pick this hormone by day 11 to 14 after conception and blood tests can pick it up earlier.
If the previous pregnancy tests were done after this time period and were negative then it is not likely that you are pregnant.
would be able to determine if there are any issues with the reproductive organs (ovaries, uterus
, tubes, cervix
) that could be contributing to your back pain
IF nothing significant is seen on ultrasound and the back pain persists then you may want to consider an x ray of the lower back.
I hope this helps
