Mildez ~ thanks so much hun. Good to hear from a midwifes perspective too.
Some of my symptoms etc sound similar to what you had and then other aspects not so similar. Still very much appearing to be ectopic however.
I havent had a fall in HCG but that doesnt mean that didint occur without me knowing.
I didnt have stringy bleeding but I did have pinkish for a bit and mucousey. Now im not bleeding at all.
I think the shoulder pain and the back pain is the biggest giveaway.
And its interesting you say it can be because of sperm issues, will certainly ask my FS about that and it will be interesting to know how it has occurred if it is in fact ectopic. Could tell us why we've struggled to fall pg naturally, aside male factor.

I have another BT this Friday - so still another couple of days to stress.

I guess I just have to let nature take its course now and at least I have some idea thanks to a few kind people on here such as yourself and so hopefully have caught it early.
TIME WILL TELL. At least I guess we got that 1 step closer.
Thanks for your wishes and support xo
