Messed up the pill. Questions !

So this month I messed up and forgot to take my pills with me for 3 days. I couldn’t go and get them. I know when you miss more than 3 days that the pills aren’t as effective. But I also got my period early and it was a lot heavier than usuaI . I continued to take them after the three days. And also my boobs have been bigger and a little sore. I’m just wondering if that’s all normal. Cause I usually only have sore/ bigger breasts during the first few days of my period. And it’s over and they are the same. And if bc will start being effective again next month?
