Shower head mastrubation during pregnancy

Okay so like a year ago my bathroom’s Shower head just started running very much harder than usual, and ever since then I got a bright idea that I could somehow masturbate from it, it makes me orgasm in less than 20 seconds. However, I think sometimes water gets in my vag..is this bad? Also, it’s a heavy pressure on my clitoris hence why I orgasm so quickly, so should I continue using it or stop?

Edit: I forgot to add that I’m 16+2 weeks pregnant
