Not sure how I should feel

Hi all. I’m 6 months pp and have been diagnosed with postpartum anxiety and ocd. I have 2 beautiful rainbow babies 4y and 6m old and those boys are my world!

My question is I’m waiting on a full hysterectomy and I got pregnant. I naturally miscarried about 3 weeks after finding out. I was approx 7 weeks when the miscarriage occurred and I’m just wondering if feeling relieved is ok? The night before I went to bed feeling pregnant and woke up feeling like it was over. I don’t think having another child is right for me and just the relief that I’m not pregnant anymore is overwhelming.
