Insensitive husband? TW pregnancy loss, anxiety and PTSD.

I have a ton of anxiety surrounding this pregnancy due to pregnancy loss in the past. Im now 18+4 and so far everything has been going good as far as i am aware but due to PTSD its hard. I bought a home doppler to check my babies heart beat if i have any doubt or any cramping which has helped me a lot. Yesterday i was checking it before we left to see my parents because i was having some pressure and felt light headed. My husband comes in and tells me its obsessive and basically mocks me for checking it just to ease my anxiety. Says its an unhealthy coping mechanism.

Heres a little back story. When i was 20, I was 6 weeks along with a previous unplanned pregnancy when i miscarried. It sent my mental health spiraling. The trauma of going through loss and feeling so empty and hurt had sent me down a dark path. Because of my depression i clung to my husband (boyfriend at the time) and i was a bit too much to handle. He was full time in school and i was suicidal. Id call him and want him to come see me because i was suicidal and not in a great place. He broke up with me because i was putting too much on him and said the miscarriage was for the best. So not only was i going through the emotions of miscarriage that no one else knew about but us, but i also felt abandoned by the one person who knew what was going on. Yes it was unhealthy behaviour and i did seek out therapy but have since been diagnosed with PTSD due to the situation and admit putting all of that on my husband wasnt ok and was unhealthy and is something i dont do anymore.

Well here i am pregnant again and every little cramp, twinge or bit of pressure triggers my PTSD. dont get me wrong, this baby is so so worth every flashback and the anxiety. He is so wanted. But i have found a way to ease my anxiety and that is by occasionally checking his heart beat on my doppler. (Ive researched how to do it and am aware of the different sounds so i know which one is his heart beat, i search for the fast gallop) hearing the little thump of his heart takes away my anxiety for a while and calms my PTSD.

Having my husband come in and tell me its unhealthy and obsessive was like a slap in my face and felt so insensitive. I have been to therapy for these feelings. I have my own coping mechanisms ive learned along the way without him and the doppler helps me. I dont use it every day. Just when the anxiety takes over. Without it id probably be in the ER multiple times a week. Im working on my PTSD with my therapist. Its just one of those things that helps momentarily.

We got in a big fight yesterday. I was hurt and had that feeling of abandonment. I told. Him that it hurt me when he mocked me like that and i explained my situation to him. I told him until he can grow a uterus, get pregnant, go through the trauma of losing a baby physically and emotionally at the same time go through abandonment issues surrounding the entire thing, get pregnant again and go through the discomfort of that with PTSD, he doesnt get to tell me how to cope, that is what my therapist is for. I told him he isnt there to fix me but to support me. His opinion does matter to me but its hurtful when instead of acknowledging how i feel, he makes me feel like an idiot for just trying to cope. Now i feel like any time i use my doppler i need to wait until hes not around.

What is your opinion? Who is in the wrong?
