Sending you a hug Suregena, wish I was still over in Yorkshire then I could have popped over and given you a hand. I know how it feels being the foreigner.
On the spotting brown blood is old blood so don't worry about that, very common when your period would have been due so 4 weeks, 8 weeks etc. With ds1 and this time I had a very small amount of bright red spotting on the day my next period would have been due (8 weeks) that freaked me out big style with ds1 but a scan at 9 weeks showed him to be totally fine. This time I tried not to stress too much and haven't had any more so my GP said it is common and not to worry unless I get pains or more red or pink bleeding. If you are really worried though then maybe go to your nearest early pregnancy unit when your hubby gets back and see if they can give you a scan?
Glad your little boy is ok, so scary when things like that happen! xx
