Should I be feeling this way??

[flutterby]

A little over a week ago I M/C at about 4 weeks. I had suspected I was pregnant about 10 dpo. (I have a 13 month old son and was showing similiar signs.) I had taken a HPT which had come up negative. The same happened with my son so I decided to wait until I was a few days late before trying again.
I began M/C 1 day after my AF was due. (Which is always on time.) My first thought was that I must of just read the signs wrong, or had experienced some wishful thinking. A few hours into it I knew this wasn't AF and a doctor later confirmed my fears. I had M/C.
I'm devestated. We were so excited about extending our family and I couldn't believe our luck when I was feeling all the early signs with the first attempt.
My partner isn't talking about it and I believe it's because the M/C happened so early and the pregnancy wasn't confirmed prior, that it isn't real for him. This is making me feel like I don't have the right to feel the devestation and heartbreak that I am and afraid to talk to friends in case they feel the same way as what I believe my partner is feeling.
I know it's only early days but my mind has wondered into the future and I'm so scared of trying for fear this happens again.
Are these normal feelings, thoughts and concerns??
