Oh hunni, I know exactly how you feel, after my miscarriage I totally forgot that I had my booking in appointment with midwife at 8 weeks and when I noticed it in my diary I had to ring up to cancel it and it just threw me! It really upset me because I didn't wanna go through the whole thing on the phone as to why I was cancelling as I knew it would just upset me - but luckily they didn't ask any questions.
It will get easier hunni, believe me time is a great healer, I will never forget but each day gets easier. The first few weeks are very raw but I was actually so relieved when my period arrived after the miscarriage it was like closure for me, for some reason that helped. Then we decided to TTC again after first period after miscarriage and low and behold I got a BFP that very month and so far this baby is growing beautifully and is still sticking around! Just reached 12 weeks today : )
Big hugs to you hunni xxx
