I am currently pregnant and working when my real life schedule allows. If someone doesn't feel comfortable with seeing me or my decision to continue to see clients, well that's their issue, not mine.
The clients that you will lose because of the pregnancy, you will make up with those who find it erotic or those that simply don't care. For sure, it is an excellent way to separate the men from the boys. With the extra hormones, I definitely lean towards the Sensual Domination aspect of my business vs. the FBSM! LOL
Additional safety is a concern, therefore I screen harder now. In addition to being hypersensitive to other energies, even through email. So if there is ONE iota of a red flag, the appointment request will be declined.
All in all, don't let anyone's opinion dictate how you want to live your life. If you feel comfortable being pregnant and a Domme, that's all that matters.
