Hi I need some guidance and IM LOOSING MY MIND.

I had my frozen transfer on the 22nd Jan and got my BFP on 6th feb, but I have been getting brown discharge for 3 weeks now and today its very dark brown with some small bits in.

I miscarried my last transfer so this is really making me panic. im on 3 x cyclogest a day as well as lubion injections but my 1st scan isnt until 23rd feb.

The nurses have said it can be normal and to hold tight but im really starting to panic. Has anyone had this and gone on to have a perfect little one!?
