Spending the weekend with my boyfriend ..

So this past weekend , Friday -sunday , I spent with my boyfriend . we had sex .. Like multiple times a day , not so sound like a horndog .. But even when he didn't finish we would change the condom for just in case . I had been taking my birth control pills every day but Saturday night I had realized I was taking the wrong ones .. I had started at week 2 , I have 3 weeks of birth control and one week sugar pills , I thought I had been taking them right but tonight taking my pill I realized I had been taking sugar pills instead of week one pills ... We had unprotected sex Sunday morning without him finishing inside me or even at all ... Am looking for reassurance or something ...
