u/One-Sentence-3509

Hi so I basically need some advice/help.

I’ve had two periods so far this month. My first period started 2nd May and ended 7th May which lasted for 6 days which hasn’t happened before, the flow was heavy the first few days. The second period I got it within 10 days of finishing my first period, I got it 18th May and my flow was very light, it was mostly dark brown/red clots and wasn’t runny like blood should be and my period ended yesterday 20th May. This has never happened to me before and was wondering if I should see a doctor now or wait till my next period comes to see if this irregularity will continue? Any answers as to why this is happening thank you?
