Idk if I am pregnant

Hey guys, I hope you all are well!

I’m in such a confused mind state atm, I really need your help. I’ve done about 4 pregnancy tests. 2 from clear blue & 2 from first response. The 2 from clear blue came out positive however the 2 from first response I did later came out negative. So idk which one to trust.

The cleAr blue test I done both of them had a faded line so idk if that means I’m pregnant or not as the first response test came out negative.

Thanks in advance for your advice!
