I haven’t been taking tests since my last period - only in the last week or so as I thought ovulation might be approaching. I have also avoided doing them in the morning based on what I read but the latest batch of strips I bought specifies FMU so this morning I took one and it was positive. That’s the first positive result I’ve gotten from a week of testing. Decided to take one again at 3 pm just to see and sure enough it’s negative.

I feel like I can’t trust the results; what is going on? Is it normal to have a positive and negative result within a 9 hour period???
