Hi. Missed my period on 21 May 2011. Got positive pregnancy home tests done,probably about five. on 22nd went to a local clinic and HCG test came back positive. Went to another clinic for second opinion on 26th May and positive test returned. Then decided same day to go see an OB and have some blood work done since i had a miscarriage i August 2010. Checked blood and urine, all fine, did a third clinical pregnancy test which came back positive. Doctor said i should have an ultrasound to see whats happening and health position of my organs. All of them came back good. Had very few pregnancy symptoms, like mild tugging sensations and pulling in the belly, a bit of backache and tender sore breasts on the sides. However there was no gestational sac noted and this was 4 weeks gestational date. He said perhaps its too early because the scan seemed to show signs of a residual reaction. symptoms have practically been on and off since, mainly disappeared that i can go to bed with a bit of fatigue and sore breasts but i wake up feeling "not pregnant" and i tested yesterday again at home just to be certain, test came back positive. Today woke up feeling not pregnant and decided to go get a second opinion. Did a trans-abdominal ultrasound and it came back with no sac seen, no sign of residual reaction and its 5 weeks and 3 days now. last night i had terrible but not constant cramps, no bleeding since. I feel like the second ultrasound has run away with any hope i could have had. has anyone gone through this?
