hello and welcome to NeuroTalk tho I am really so sorry to hear what brought you here

I lost two babies and so I deeply understand what you are going through.
The emotional trauma of a miscarriage is hard enough, but there is also a physiological aspect to this as the pregnancy hormones suddenly not being there anymore can do all kinds of weird stuff too.
and you are grieving the death of your baby.
grief has many phases
here is some info that may help your boyfriend understand

Do you have anyone trustworthy to be able to talk to there? a pastor or close family/friends? Have you told your doctor how you are feeling?
it really is good that you are here releasing how you feel as that is a step in the right direction for your healing.
we are here for you
I will keep you and your family in my prayers
