Following Dr.s orders I think would be the right thing to do what can it hurt
I'm more of the line that if your going to miscarry there is not alot you can do if anything to stop it, so with the ones that I have had I've always just gone about my business and done what I had to do, your boyfriend maybe right, you may have passed everything, you may have had a blighted ovum, thats when everything stops developing early, usually before the baby has formed, so before six weeks, the body can still think its pregnant for a times as the placent can grow, it just takes a while for the body to realise that no baby has grown, I would def do as they say regarding seeing an obgyn, if indeed your hcg level was 1300, this is quite low for 8 wks, hopefully everything is progressing and you find that you have a sticky little bean, good luck
