Data/ cycle messed up?

I was pregnant in July but had MC at 7 weeks. Thinking this has messed up how Glow calculates my cycle?

I'm pretty regular 29-31 days both before MC and after. But when I entered my periods Jan to June, my ovulation window and AF window for this month moved...

Should I just delete the data from before MC? Imo my cycle hasn't changed - it just "paused" due to pregnancy / mc....

Please give me your advice, ladies ☺
