I need your help ladies!!

Ok so I waited my 6wks to have sex right!! So that’s was around March 14 2025 ok so fast forward to April so I start feeling nauseous out of nowhere I took a dollar store test it had a faint line so I was like make I still had some kind of trace or something then I just test again with the blue dye pregnancy test that had a faint line but u can see it. So I went and took another one this time pink dye and it’s most definitely a pink faint line or will that be because I just had a baby in January or could this be a new pregnancy because I’m freaking out!!!! Has anyone been through this before????
