I'm not sure please help 😩

Claire
So I done a pregnancy test on Monday and there was a vvvfl I done one a couple of hours later and the same thing happened (I used clear blue early detection ones) the next day I brought the first response tests but they wasn't early detection ones and the came back negative. Yesterday I decided to get more clear blue early detection tests as my af was due that day (yesterday) but there was no sign of it, as soon as I brought them I done one and got a vvvfl again so decided I'd do the other test first thing in the morning (this morning) hoping the Line would be darker but you can hardly see it again, I'm so confused I don't no if I'm pregnant or not 🤔 I took a pic of this mornings test. What do you think? I've had a chemical pregnancy before in December so I really don't want to get my hopes up! Can anyone give me some advice or has this happened to you before please?Â
