nomorepain,
I am so sorry to hear about the loss of your precious baby.
I have been in a similar situation to you. I lost my baby Noah in February at 20w 5d. My sister at the time was about 14 weeks pregnant. After I lost Noah, I didn't want to contact my sister, and part of me was so jealous that she was pregnant and I wasn't. It took my DH and I almost 2 years to fall pregnant with Noah, and my sister fell pregnant without trying.
My nephew was born in August, and I admit, I was a little apprehensive about meeting him... thankfully, I had a cold at the time so I got some time to really wrap my head around the thought of him. When I first held Taj, I went to call him Noah... thankfully, my sister and my whole family have been very understanding about my feelings.
With support from your family and friends (IRL and on bellybelly) You will find that you will be ok with time. My thoughts and prayers will be with you through your IVF journey. Fingers crossed it will be a short and successful one
Lisa
