Looking for advice

So I took a test this morning just for shits & giggles. I haven’t been tracking ovulation or anything lately. Kind of put off TTC for a couple of months. Waited & checked it. Low & behold 2 lines. Faint but it was there & could be seen. I freaked out and ran to the store & bought a FRER & ClearBlue. Both came back negative but the cheap $1 test clearly has two lines. I’m confused. Could I possibly be pregnant? Or was it a fluke? My periods due in about a week. Has this happened to anyone else?
