Help, I need advice! Is it a false positive??

In early March the husband & took a trip to FL & while there I thought I may be pregnant so I took a test & it was negative. I had the spare test so I put it in my suitcase & brought it home. Well I just used the spare test & it’s positive...like BFP!!! I’m concerned flying with the test strip caused some kind of malfunction it give me a false positive. I of course plan on taking another test as soon as I can but in the mean time of having to wait for stores to open what are your thoughts?
