I had unprotected sex on June 29, 2013. He did not ejaculate, but there seemed to be a gracious amount of pre-ejaculatory fluids.

About a week and a half later I experienced light, pink and brown spotting that only came off on the toilet paper. This lasted about three or four days max.

More recently I've had:
-increased stretchy vaginal mucous
-for the past two weeks--nausea, sometimes vomiting,
-constipation,
-extreme fatigue (14-16 hours of sleep and almost immediately tired again.)
-super sensitive breasts and sense of smell,
-headaches (dull throbbing in the back of my head)
-back aches (like a slight crampy feeling.)

My period was due on the tenth-fifteenth of July. My cycles are about31 days apart.

I just really need someone's help to clear things up.

You would NOT be having these pregnancy symptoms this early. Have you tried an HPT with first morning urine? Seriously though, it is too early to tell.

Took one--it was a dud. Thank you though. I'm so paranoid

Wait until your period is at least two weeks late, then test using first morning urine.
