Possibly pregnant

So here’s the low down

I had sex with my boyfriend after my period, no condom or BC ! Within that 24 hrs I took plan b and started my BC. Now with that being said we have been having sex literally everyday maybe 1-2 a day since then unprotected. Now as of last night after we had sex I went to the washroom and noticed bleeding which I don’t have now, I’ve noticed my boobs are sore as well and I’m don’t expect my period till next week . . Should I be worried or am I tripping?! Also I have missed pills but took two maybe the day after
