Skipped birth control and had unprotected sex

Ok I had some issues with getting my birth control refill so I ended up missing 3 or 4 days of it. I had unprotected sex and my boyfriend did cum in me- about 3 times in the past week (this is bizzare for me because I quite literally have 0 sex drive normally) anyway I’ve taken it all of this week and I wasn’t sure if the 3 days was a cause for concern or if I’ll be ok. My body reacts badly to plan b so I can’t take that. I’m not scared of getting pregnant but It’s definitely not the right time for a child. If anybody knows anything let me know I’m not sure what to expect!!
