88 cent pregnancy test

I have two boys. One that's 2 1/2 and another that's 5 months. I'm not wanting to be pregnant right now but we had some condom issues annnd here we are, thinking I'm pregnant 🤦‍♀️ regardless I'll love this baby so much (if I am). BUT question for you ladies. I took a 88 cent pregnancy test and it came back with the faintest line ever! It was in the time frame. But I still don't believe it. What are your experiences with these test? With my boys I never got faint lines unless I was actually pregnant.
