should I still be worried?

So about two months ago my boyfriend and I had sex for the first time and the condom broke, I was stupid and wasn't on any type of birth control at the time. So the morning after (with in the recommended 24hours, I think it was around 17 hours after but it was a pill which is affective for up to 5days, ellaone) I went and got the pill and few days later my period came which was on time but early by one day, I had normal symptoms like cramps and pms and my period seemed normal like I didn't think it's implantation bleeding as it had clots and varied from light and heavy. The only difference was that it lasted for a full 7 days and was a day earlier but I think it was to do with the pill. Another month later I got my period just like this again but it was two days earlier I think that could be to do with the pill as well? And that was really heavy for the first 3days and then a bit lighter for the others and also lasted around 7days, that had clots in it as well like a normal period.
Because I had these two periods does it confirm that I'm definitely not pregnant?
