Faint positive but AF showed up???

Ok guys so I’m so confused…… I’m 9DPO and AF showed up yesterday earlier then normal and I have been getting faint positive since 7DPO and this morning it’s darker so it’s deffo there and this showed up in the time frame so not evap line. But I’m just confused but when I was pregnant with No.2 when I had my scan it showed up that I was further along then I was and when calculated I did have a period when I was pregnant early on with him…….

Has anyone else had a period early on in pregnancy?

So confused……
