1234babies, dont be sad, my case was very similar.
i had miscarriage last week and my bb was 10 weeks....i couldnt see his/her fetal heart until 9 weeks, but the problem was, i got bleeding.
i had no pain at all, no feeling bad since day 1 until 25 dec, then very bad bleeding on 26 and 27 dec, it was so so so harsh....then i knew i lost him/her.
i then went to see doctor on 28 dec and had the operation on the next pm...slept one night in the hospital and now i am ok, acting normal, just wait for my period to come.
i did ask my doctor re medicine or operation, my doctor suggested to have a clear one - operation cos it will not affect the next bb as he said......and i have another friend who had medicine to take out the undeveloped bb, she had another abortion today....so you must deeply think.
good luck, add oil, i am sure you will get another healthy bb soon, once you have recovered fully, around 3-6 months.
