Not feeling connected to this pregnancy or baby


So a little back story. I got pregnant on our hunnymoon, wham bam thank you ma’am and had a boy who is now 2. I was pregnant December 2016 and miscarried in February 2017. Got pregnant again in June of 2017 and miscarried in September 2017. Pregnant again in December 2017 and currently 14 weeks pregnant. It’s not that I’m not excited for this baby, and feel no connection to it, but I just don’t feel as happy as I think I should. I was so excited with my son and took bump pictures every week and with this one I haven’t done a single one. I just keep having this feeling like I’m waiting for the other shoe to drop and for me to loose this baby too. I feel like a horrible mom to this baby/pregnancy because I can’t give it all of my attention due to being worried all the time. Anyone else going through this or been through this? Or am I just crazy
