Not even sure anymore

Miss T

Ok so I don't think I will get an answer but here goes...got a BFP on the 14th of November. Which would have been around day AF due. Had sex 1st 2nd and 7th. I had a brown possible implantation bleed on the 11th. Based on LMP I should have been 8 weeks last week. Had some spotting and went to EPU for a scan. They found 2 empty gestational sacs and measuring about 5 weeks which doesn't fit with any of my sex implantation bleed or LMP I was in shock and uncertain about how I felt about twins and whether it was viable. I went for another scan today still 2 empty sacs 1 had got bigger 1 has got smaller and I've been bleeding for the last week not heavy but more than brown/pink and more than wiping. Got to go back again next week for another scan because 1 sac has grown as expected They have to consider it still viable even though it's empty. Any one able to offer any comments experiences or support. I am mentally going the bed. Can't feel happy for a sticky bean or sad for a miscarriage because I don't know what is happening or even when I might have become pregnant can't work out the dates symptoms
