Okay ladies. I need either some advice, reassurance, or just some kind words today. Lately, for the past two weeks, I've had sore breasts, back pain, nausea badly, vivid intense dreams, and all the above about being pregnant. I thought it may be just the nearing of AF (due 11/14).  So yesterday morning I took a HPT and got a BFN at first then an hour later I checked again and It was faintly positive, so I immediately called to get a blood test to finalize it because I was THAT excited. Got the results today, BFN. I cried. It came all at once. Right when I got home I took another test and it was now a BFN. So with that being said I'm a bit devastated and don't know if that's normal and if any other female has had that experience?! Let me know ladies ! Im all ears !
