Oh mama, two weeks is still so fresh, please be gentle with yourself. What you went through is really a lot: the uncertainty waiting from week 5 to week 10, the shock of the diagnosis, and then two procedures back-to-back. That's emotionally heavy even when the decision felt right at the time.
A lot of mums I know who've had missed miscarriages say the grief feels complicated because there's no "before and after" moment, you're mourning something you didn't get to see develop, while maybe also feeling relieved about the decision. Both feelings can sit together, and that's okay. Some have found it really helpful to talk to a counsellor who specialises in pregnancy loss, not just because something's "wrong," but because having someone neutral to process all the mixed emotions with makes a difference.
Right now, be kind to your body, it's been through surgery and hormonal shifts. Rest when you can, and if the emotional weight doesn't feel lighter in another week or two, or if you're having trouble sleeping or eating, definitely mention it to your GP or the doctor who did your termination. They can point you towards support that actually fits your situation.
You're not alone in this, and how you're feeling makes complete sense.
