I totally understand your vent, it's one year since my gabriel died and I am possibly losing another. Last week kids in my form group were shoving scan photos of their sisters 12 week scans under my nose, god that hurt! I haven't even managed ten weeks with the last four babies. As their teacher, they weren't even supposed to know I was pg, if I had been a student the phone would have been thrown! To top it all, a colleague brought in her gorgeous 5 month old babe that was born the same week I was due. I find it so hard that friends and colleagues of mine are able to get pg again after a loss and then carry their babies when mine keep dying.
So vent away and don't feel guilty.

Sending you hugs
