Weird periods

I came off the pill in August 2024 and since then my periods have been irregular but not like this.

This time I started bleeding and then stopped for an entire day with just browny discharge every now and then, last night I had sex and there was blood everywhere which I wasn’t expecting!

Then this morning I wake up and I’m not bleeding again.

I haven’t experienced anything like this and am not sure what to think of it 🫣

Any thoughts? Has anyone experienced this before?
