Diving board??

So.. Before anyone scolds me. I'm super worried to begin with. I'm 15 weeks and yesterday in a moment of fun I jumped off the diving board at my moms pool. It's literally a foot high. I of course asked everyone if they thought it was okay and they did. But now I'm like.. should I have? Haven't had any pain or bleeding. Just wanted to get everyone's (kind) opinions on it. I have a heartbeat Doppler. At home! And I ofcourse for whatever reason didn't bring it since we were only staying a night. But now I'm kicking myself that I didn't.
