Vfl and now I’m bleeding...

I’ve been testing for a few days (currently 13 dpo/ 1 day before AF) and I’ve gotten vvfl since yesterday. The line was a lot darker today so I thought it was finally my turn... I just went to the bathroom and I’m bleeding... I’m still going to test in the am if the bleeding stops but has this happened to anyone else? I had a chemical pregnancy 2 months ago and this feels different.
