I keep getting period pain (like I’m about to come on) but every time I go to the bathroom, there’s nothing there.

I had a vfl a couple of nights ago, I retest and it was negative so I didn’t think much about it.

I’ve just taken another one and a vfl came up within a minute or under.

It’s starting to make me think I’m losing it. Or I’m seeing things. I’ve tried taking a picture but because it’s faint it’s hard to get.

Any help would be greatly appreciated.

Thank you 🙏🏽
