Your late bedikah is ok. Showering does not invalidate a bedikah.
I have no established veset and I forgot to do a bedikah on my onah beinonit but I did one four days later and it was clean. However, I had showered (but not bathed) during that interval, and I have heard that bathing in the interval invalidates the bedikah done after onah beinonit. Has my showering invalidated my bedikah, and should I now consider myself niddah and start checking for seven clean days? Or is my late bedikah still ok despite the showering so that I can resume relations with my husband?
