Need advice

Hey ladies, I’m needing some advice. Thursday night I took a pregnancy test and it came up with 2 lines. I took 2 other tests Friday morning and they were negative, and I had light spotting then. Friday afternoon it got heavier and so I thought my periods had started and that was me out for another cycle. But today I’ve only been spotting, it’s very light and it looks like a brown colour. Im not sure whether to take another test or not? I don’t want to get my hopes up 😔 any ideas? Below are my test pictures, so the single one is from the Thursday night, and the one with the 2 tests are from Friday morning 😩 xx
