I'm lost 😑

So I used a first response test (curved handle) back in November (long time ago, I know). Well the first test I couldn't really tell if it was positive or negative. I think I was looking way too hard and getting line eyes. So I just went ahead and took the other one 5 minutes later. Well the line popped up within the time frame and it was pink 🤷🏽‍♀️ now I've had problems getting pregnant in the past so I'm trying for my first. And everyone keeps telling me it was a chemical pregnancy but I've heard with the first response tests they are giving false positives. Has anyone experienced a false positive with a test ever?? Is it possible to even have a false pos. On pregnancy tests? I'm just so lost. Idk if I was ever even pregnant
