Is my period normal?? I'm very scared!?

Even though you did not say so, I am guessing that you are in your early teens. If this is correct then, as a doctor, let me assure you that you are very normal. In many cases it takes up to two years for the menstrual cycle to regulate itself. Obviously you cannot be pregnant if you are a virgin. So, relax and try not to stress. You are fine and everything sounds like it is progressing quite normally. You are just fine. Hope this helps.

It could be normal. For instance if you have just started your period even if it's a year or two old. It can be very irregular and stop at points. You can start at 12 have it stop at 14 and not get it again till your 17 so really it's come and go
