Is it normal to have an 8 day cycle??

Dec 19th it started off very pink for about 2 days before turning red. It has been very heavy this month, worse than normal. I had a miscarriage in October this year but had normal cycles up until this month. It was due to start on the 19th so it wasn’t late or delayed in anyway. I don’t have any cramps or pains either, I don’t suffer badly as a rule either.

I do t believe I ovulated this month ask kept a regular track of it but it never peaked, could that have something to do with it as I know that you don’t ovulate after every cycle.

Any thoughts and advice welcome please.
