I asked my Nurse Practitioner (we're switching to midwives here, but she is who I see now) and she said the inner hip pain is just ligaments stretching. It scared me too, esp because up til 9-10 weeks I was having constant cramps like you'd have with your period!
She seemed very VERY *unconcerned* about it, like almost blowing me off about how NORMAL it is. So maybe that will help you out. make you not worry just a tad?
Never found out what the back pain was... until 9 weeks I had a month of urine testing done every week and was spilling just a little blood in my urine, which she said was NOT a bladder infection (not enough white blood cells or bacteria), and I had a kidney ultrasound and it wasn't my kidneys... the blood has cleared up now (was trace when I last gave a sample) and that coinsided with my back calming down mostly (its still sore sometimes but not *cramping*) so maybe I was at the tale end of a bladder infection that cleared up when I upped my fluid intake??
I'm sure it must be hard to be SO worried after 3 losses! Up until that 9 week ultrasound (and I found out I was preggers at 9 DPO so it seemed like a LONG wait) I was SO terrified and worried! I did have a very early miscarriage about 10 years ago, so it didn't help, but the worry weighed heavy on my heart! So I can't imagine how worrisome things must be for you right now...
for you, I hope your appt comes quickly and you get to hear the little one's heartbeat to ease your fears. I'll be thinking of you, and hoping you get thru until then without *too* much worry.
