Is it my turn?

I hate that I read into every symptom... my husband and I have prayed so hard for a baby... we are young, and I know birth control can take up to a year to fully get out of your system, but yesterday and today I've had off and on light spotting. it stopped this evening. I'm nauseated, sensitive to smells (I'm a CNA so smells have never bothered me before) and my boobs feel like they've been kicked with soccer cleats. I took a pregnancy test yesterday at 9 DPO and got a BFN :( but I'm still hopeful. as of today I'm 10 DPO and still 4days out from the expected start of AF. but my symptoms get stronger every day. does anyone have any advice or suggestions to help me stay calm?
