Okay, so my story is that I tested 8dpo, and I got a positive. I tested 3 days following and everyday was negative....until today, there is a line like this. I don't understand. I thought it was a chemical and now I'm like wait there's a line again. Does this brand of tests produce false positives? Please let me know thoughts. Thanks so much.
