So two days ago I took three tests all very very faintly positive. Yesterday I took two on the morning BFNs. Took one on the evening time ( better quality one ) and the second line didn’t show up until after the 5 minute time was up. This morning I’ve took two more and BFNs again. I just want to know what’s happening with my body ☹️ Does it sound like a chemical? I’m so worried incase it is the case.
