The 'It's wrong to make me feel lesser/excluded just because I haven't had or done x/my experiences are just as equal as yours' line of thought is very topical in our culture and needs unpacking.
I was always told in late teens/early 20s especially at work 'until you're a parent you will never really get it.' Hated hearing that. Hated it. It felt patronising and exclusive and belittling, although it was never meant that way. Then I had multiple mmcs, including one late one. Never succeeded in having a pregnancy to term, but I had those few weeks of sharing my body with someone else whose heart was beating, and was socked in the face by the visceral, primal emotion connected with it. I never in my life realised it was possible to feel so powerfully, to be willing to do anything at all for that little life. Or how it would feel being separated even when the baby had died, when everything in me was screaming that I had to be where the baby was. Not logical, not rational, not a whole lot of thought involved, just physical pull and instinct.
I have zero desire to silence other women about pregnancy or motherhood, or to separate myself from women whether they are mothers or infertile, because of them being 'triggering'. Any feelings I have of exclusion because of my infertility are my responsibility to process and manage, not for others to protect me from. Of course I'm not 'lesser' as a woman for not having successfully given birth (that's the patriarchy calling, only women churning out perfect, able bodied sons to inherit are worth anything) but my experience as a woman does not include motherhood. That's the reality, there is loss and disappointment in that which is mine to process and live with, and my respect for other people's experiences and sharing of them can't be conditional on them managing my reality to be more comfortable for me. And the people who supported me through the losses, the grief, the medical procedures, shared their own experiences of how to move on, held my hand in an operating theatre, wrote my son's name in a children's chapel book when I couldn't, all of them were women. Because infertility is also a women's experience and only really understood by women who have lived it.
The women who told me I wouldn't get it until I had a child were absolutely right, they were sharing a life experience I couldn't understand on a rational, informational level from other people's experiences. Those few weeks were enough for me to realise I barely had a taste of what a woman must feel when a pregnancy comes to term, experienced birth, fed and raised that child - I don't have a clue. I can't possibly. I just know enough to know that I really don't know.
