TTC in an 24/7 D/S relationship.

I am not looking to start a debate on mine and my husband's lifestyle. We have been together for 8 years, married for 5 years, and in an AMAZING Dominant/Submissive S/M relationship for going on a year now. We had our SURPRISE daughter five years ago and we were strictly Vanilla at the time. My question is there anything that we should refrain from once we do get our BFP? Our playtime includes: Biting, hair pulling, scratching, blindfolds, ball gags, restraints, nipple clamps, butt plugs, oral sex, orgasm denial, wax play, ice play, flogging, anal sex, spanking, paddling, breath play, and mild genital Biting. I've done extensive research online and haven't really found anything helpful. Advice would be welcome.
