7 weeks pregnancy but only sac is visible

Hi all, Finally I got the answer.. yesterday I had a heavy bleeding with lots of blood clots.. minor cramps also felt as if I am having menstrual cramp.. the bleed continues until today and hasn’t stop.. HCG level dropped and ultrasound showed a shrinked sac.. went to Dr Goh and she said it’s a blighted ovum.. we grieve as a parent to be but it doesnt change the fact that miscarriage is something beyond our control.. Thanks for all the supports and sharings.. this gives me a valuable lesson that pregnancy is tough but worth all the roller coaster of emotions 😊 I am okay and resting well.. hope everyone is expecting have a safe and healthy journey!
