Anyone else experienced this?

I’m just wanting a little reassurance at the moment. So my period has come three times in the last month and a bit. This is very unusual for me and my cycle is usually once a month. This last time it has barely been a ‘normal’ period for me and has just been light and like ‘spotting’. I still had the normal symptoms beforehand like mood wings and sore boobs. The other two times it was like my normal period.

I’m just a little confused and worried and just wanted to see if anyone else had experienced this?
