Was I rude or just honest?

I had a consultation today with my daughter’s future principal and we had a talk about the school and what’s expected from the parents. It’s a private school so we’re already paying a lot for her to go there. I knew they want parents to be involved and help with a mandatory 2 events a year to help (more if possible). The second he saw that I work from home (just as my employers address was the same as mine-the document stated I’m an engineer) he was like O you’re a SAHM that’s great we need a lot of help…I did say I would love to help but for the first year I’ll have to do just the minimum 2 events as currently I’m pregnant and I’m due right when the school year starts and I actually run two businesses from home working from 7am till 10pm to give a good life to my kids and don’t have days off but once this year is over and we’re not in the baby stage I’ll do my best to help as much as I can. Was this rude of me or just being honest? My husband said it was mildly rude but acceptable. I mean I’m not truly a SAHM..I raise my kid from home while I work two jobs and I’m pregnant….even working parents have more free time than me. He didn’t even look at my husband to ask him if he can help which already told him he’s off on Wednesdays so this was little weirdly targeted at me.
