So today i went to the health department to check baby, they are saying im 12w 4d, but my last period was Oct 5th which wouldnt make that. They sent me for an transvaginal ultrasound and the tech didnt do a trans ultrasoud, they did an abdomen one. The health department said the baby stopped growing 5 weeks ago if i was 12w 4 days which thats when i found i was pregnant cause i missed my period on nov 1st. So they sent me to er to get a d&c done and the er sent me home cause it wasnt an emergency. So i went to get a 2nd opionion and they drew blood to get my levels and doing an ultrasound in the morning cause they are confused of why the health department isnt going by my last period.
