So I'm about six days before my first missed period. Me and my hubby have been trying to get prego for a bit. We finally got a positive for ovulation test, that was almost two weeks ago and I've been experiencing nausea, my boobs hurt so bad I wanna cry!  Bad !!!! I am going to restroom way more than I use to before. So today I decided ok maybe I'll take a test .... First response and it was negative ..... am I just crazy or maybe testing to early ???
