can you enlighten me - I am very confused. I had a mc last month at 5 weeks, bled on Tues 13th Dec for 4 days, so I assume on my 26 day cycle my af would be due Jan 7, last night I said to dh that I bet I am up the duff as felt pregnant, bought a First Response test today and was not going to test until the weekend but of course could not wait. Just did it and got a positive, and a very strong line as well. how can it be? Could I still have preg hormones kicking about from last month's pregnancy? Because i am testing so early the line should be a faint one if any. Can it really happen this quickly??
