Masturbating and peeing on myself

Okay so bare with me and no this isn't a pity post. Awhile back me and my fiance had bought a vibrating bullet and sex with that tiny thing was the BOMB. A week ago before I knew I was pregnant while he was at work I had started using it on myself in the mornings after he kissed me goodbye. I never could cum but I pissed all over myself and the bed and felt so embarrassed. So before he got home I cleaned everything up and just didn't tell him.

Now my questions are 1 is pissing while masturbation normal?

My next question will be after this. In the past four days I've been actively miscarrying our child and though he says he doesn't know about trying again and I'm not comfortable about really giving sex to him when this is all over and may just be how I'm feeling at the moment but would it be alright if I deter from sex for a little? And could my over use of the vibrator be the cause of my miscarry
