Hi there
Wow - what a crazy time for all of this to be happening to you. Did you take the test yet? With all of the probable signs you are having (movement, gain in abdominal girth, sx of pregnancy - heartburn, etc.) it sounds like you're prob pregnant. With being in the medical field, in neonatology specifically we deal ALOT with obstetrics, a urine test is still only a probably sign of pregnancy. THe only absolute way to know is to get an ultrasound and have visualization of the baby, and doppler the heart. There are other signs of pregnancy but an OB doc or midwife would have to do that assessment.
The only thing that comes to mind for me if it
isn't pregnancy is the possibility of a hydatiform mole. Google it. I remember learning about it in nursing school, I just remember reading that it can exhibit signs of pregnancy and women without prenatal care will go in to their doctor at like 38 weeks and ask for an exam, where now the mole is like 7lbs.
I'm sure you are pregnant, and I hope you are pregnant, what a wonderful gift a child is. I was not trying to scare you with the alternative, just let you know what cam to my mind right away as the alternative.
Best of luck to you with everything
You are in my thoughts and prayers. You are more than welcome to PM me if you have any questions I can try to answer.
