😔😔 help me please 😔😔

I have two children one 4 one 3. It took me 5 years to conceive my first and when he was 6 months old I found out I was pregnant with my daughter. My husband and I never use protection and open to “if it’s gonna happen it’s meant to be”. I have just felt off. Super tired, on edge, and getting disappointed that it “hasn’t just happened” yet. With both kids I didn’t have any symptoms other than missed period, and my son was without a doubt a positive test. With my daughter I used these test and got faint lines like these. Idk if I just want it so bad and

I’m seeing what looks like faint lines but still thinking they could be evaporated likes. Suggestions please!!!
