What should I say back to this friend?

I had planned a small hike for my milestone birthday because of covid.

However I had a friend one of 3 people I invited who I sent a reminder message to of what time to meet and where 2 days before we were all set to meet up.

After my reminder message, she tells me she just got her period and doesn't feel like going on a hike in 2 days.. but she can try to visit the area.

What do I say back? I feel is meeting a guy for a date and changed her plans with me last minute.

She has also flaked on me a few times this past year, even tried to schedule 2 zoom calls and then she said that time didn't work bc she was going to the mall or doing something else with her parents.
