Period early, stopped for 3 days, then started again when properly due!

[Newtoday]

As the title. I temp and could see it wasn't a proper period as my temps remained high.

I've had intermenstrual bleeding before, which was always old blood. This was two days of proper period blood, then nothing for almost 3 days. And then, around the time my period was due, it started and temps have started going down.

The extra bleeding started at around 9dpo. Here's my chart, if that sheds any light.

I had a positive OPK on the day the bleeding started.

TIA!

Maybe you should post on pregnancy?

Ok, I'm not pregnant though! But perhaps someone may have had similar. Thank you.

OK sorry. What are you wanting to know?

I'd like to know if anyone has had similar and found out what it was. I live in a country with private medical care and ahead of appointments it's useful to have all the information ready to present.
