Not Really Having A Period

Ssoo I’m supposed to be on my period. I technically started yesterday, but I was barely having any cramps and only a tiny bit of blood came out and normally I have a heavy flow for the first day or two. Now I’m not bleeding at all. I do have a slightly irregular period, but normally I start bleeding a bit heavier by now. My boobs are still swollen/sore, I’ve been feeling incredibly fatigued for the passed almost week now, minor lightheadedness if I move too quick (I’m always well hydrated, eat well and have no iron/low blood sugar issue) and I’ve been forgetful probably from the fatigue. Freaking out a little because my husband and I had sex during my fertile days (approx. May 27th - June2) I mean I’ve been wanting to start trying for kids, but it would be very surprising if it was so soon...could I just over thinking it? I’m waiting at least a few more days to take a test.
