I completely forgot to make a bedika for onah beinonis and it’s already quite a few weeks later. Do I still do some kind of bedika? I already got my next period…
Since you already got your next period, that bedika is no longer relevant and there is no need to do one now. If you wouldn’t have gotten your period since then, the halacha would be different and a new shayla should be asked.
All the Best
