Charting After Miscarriage

🌹Rose🌈🎶 • FTM since 12/23/18 <3

I miscarried on Valentines Day and once I was done bleeding started charting again. What I can't figure out is while my temp has gone down it is still consistently higher than what my temps were before. Any thoughts?

The pink line was a cycle where AF showed up, the orange line is the cycle where I got my BFP, and the purple line is where I've been since I started charting again.
