Hi Ladies,
Thank you all so much for your concern.
I went for the scan at the pregnancy advisory centre, an external scan picked nothing up so the doctor performed a vaginal scan, she took ages and I had to manoeuvre a couple of times and at first she struggled to find anything but then found what she thought 'may' be a yolk sac but she thought it looked like there was bleeding into it. She could not find a heartbeat. I have now been referred to the early pregnancy unit at our local hospital (next Thursday) The doctor suspects that I may have had a missed miscarriage (where the foetus' heartbeat has stopped but my body still thinks it's pregnant & so continues to release the pregnancy hormones.) It's all very unclear at the moment and I still struggle to accept that I may be (or may have been) pregnant. It just seems so unlikely

and I don't 'feel' pregnant.
Matildamouse... did you tell your husband at the time when you had your scare? I still haven't told mine but I'm starting to wish that I had, I hate keeping things from him but I just know that he'll question whether I've been faithful (which I totally have!) and I couldn't stand the thought of being accused along with the worry of being pregnant at 48

.
Taz... Since you mentioned your friend I have been researching pituitary disorders and I do have a lot of the symptoms including a phantom smoke smell that very frequently plagues me, I had an mri about three years ago relating to this and it picked up nothing at the time. I guess I'm just going to have to wait and see what Thursday brings and then go from there.
I confided in my friend last night as I couldn't keep it to myself any longer, she's being very supportive and is taking me for the scan on Thursday.
I'll let you all know how it goes. Thank you so much again for all your concern and support, this forum and you ladies are amazing!
