Hi ladies. I’m 34 days delayed. Had unprotected sex first week of October with fiancé. I haven’t had any sign like nausea or sore boobs. I just feel irritated often and light-headed or having a mild headache. I feel emotional at times and always tired. I am always a small ball of energy, now I’m just always tired. I know there’s something different in my body. I tried using a few PTs two weeks after the unprotected sex but it turned out negative. Should i be worried? Maybe there’s something else other than pregnancy?

Edit: I took a PT this week using 3 different brands of PT kits and all turned negative.
