I went to the er yesterday because I had slight spotting,nurse told me only thing she could see on ultrasound was gestational sac but she said because I'm suppose to be 6w 5d they should have saw something else like yolk sac,fetal pole etc,but by my ovulation date I should be exactly 5 weeks because my periods are irregular and I ovulate late,I don't know what to do,I go in for more blood work tomorrow to see if my hcg will rise it's at 1274 right now.i hope everything turns out to be fine.
