Period or ovulation bleeding?

B

I have not ovulated since I began charting 5 months ago. On the 19-20th I had tons of watery CM and my first ever positive OPKs. On the 21st I had slight cramping and a medium amount of bleeding and I assumed it was my period (mine are very light and short since I don’t ovulate).

The last two days my temps have been very high compared to the last 5 months in the follicular phase, and I’m guestioning if the bleeding was my period or possible ovulation?

I have not had any change in temperature, sleeping conditions, restless sleep, etc.

Any insight would be appreciated.
