So i took a trip to the ER yesterday with cramps in my abdomen. i’m estimated 4weeks 4days pregnant. they preformed a blood test n my hCG levels went from 120 3 days ago to 645 yesterday. which apparently is really good. they went to do an ultrasound and saw nothing. i think it’s too early to see anything but one of the doctors instantly said it could be an ectopic pregnancy without doing a scan to check my tubes. he called for a second opinion and the other doctor checked me and said i have no risk factors and everything looks perfect expect for the fact that they can’t find the baby. i’m supposed to go back in 48 hours to check my hCG levels again and have an ultrasound. should i be worried or is it just to early??
