I'm a Krav Maga & kickboxing instructor and also am a Brazilian Jiu-Jitsu white belt (training consistently for about 6 months).
I'm concerned that I can't train! Luckily the school I teach at is not a competitive fight school and we allow students to modify anything they need to because of injuries, ability, etc.
I'm worried mostly about BJJ - anyone out there who's trained during the first trimester?
Due to the nature of my job and the fact that accidents can happen, I'm telling my boss and coworkers on Tuesday or Wednesday when I'm only about 4 weeks along. We're all close and I'd rather let them know sooner than later to be safe. I understand the risks of a miscarriage are higher, but sadly my boss's wife had 2 so at least they'd be understanding and sympathetic and a good support system.
