I am confused, test expired

hi everyone. i need some advice. 2 days ago i took a pregnancy test at 9 po and a thin line came out and the control line was well marked. my legs were already shaking with excitement. then i realized that the test was expired. i had other pregnancy tests that were not expired and i took another one. this one remained white. i checked both tests again and i discovered that the expired one has a sensitivity of 10 Miu/ml and the other 25 Miu/ml. today i repeated both tests. the expired one came out positive again with the line a little more marked and the non expired one was still negative. i have hope, but at the same time i don't want to get my hopes up. what do you recommend. thanks

Today i tested also Lh.
