I think that you should tell him, I think you need his support and although it was upsetting for him it was worse for you as you had all the physical pain too. And he will need to know of you do mc again Hun so personally I would let him know. I know it might make him feel scared about ttc again if there (god forbid) was to be another mc, but that's natural and I'm sure you could talk him round. But that's all irrelevant anyway coz you are gonna get your sticky bean in 2 months and you should share every second with your oh.
Of course that's just what I'd do hun, its whatever you feel.
