Brief update so I have spoken to a doctor and she was was really nice and reassuring.
She has told me it's very common in early pregnancy to spot and it's nothing to worry about as long as it's not heavy bleeding or cramping. Apparently the embryo can embed and cause bleeding.
She has issued the prescription for my Prednisone 10mg tablets and is going to clarify how long my Fertility specialist wants me to take them for.
My husband has put his foot down and I'm to be bed rested this weekend!
I guess the worrying doesn't sadly stop at the positive test 😮
Thank you to everyone who sent well wishes I really appreciated the support xoxo
