Opinions please

So I decided to get off the nexplanon implant because it was making me constantly bleed , and I just gotten it taken out and I was switching to pills . My dumb self had unprotected sex like 5 days after and he said he pulled out , I took a plan b the next morning (within 24hrs) and I started my pills that night , I already have a son And I cannot have another rn , my period should start in 1-2 days but I’ve always been irregular . Do y’all think I should worry or am I most likely in the clear
