Opinions? ☺️

Hello..

I’m a newly wed, a first timer ttc. I have a longer cycle and an exact of 6days AF. If you look at my cycle calendar, and I had tested PT as early as last week and it came out to be BFP as I experiencing some mild cramping on one side, bloated, headaches and fatigue. And super horny for weeks (Feel lucky for my husband)

And few days ago, (Monday), I didnt feel any of the symptoms anymore. And i took another test, and it came out BFN.

Is it normal for that to happen?
