The let down..once again

8mos ttc. 30 with an almost 6yr old/DH 36 with no kids. Had an annual check up 2 wks ago and all tests were normal and healthy. Been off seasonique since feb 22,2014( a few times I forgot pills for at most, 5 days). I had ALL the symptoms: nausea, back and headaches, hunger but food aversions, cravings for spicy and seafood, bbs hurt to the touch, cramping 5 days straight(not AF but noticeable), fatigue(I slept in car between errands), temps.... But AF just reared her heartbreaking head right on-time(and glow had it all wrong again)... Pretty sure it's not me and DH needs to do a SA but I know we're both terrified for a bfn from his dr and well, he'll never have his own natural children... We've been dealt a bad hand a lot in 3 yrs and this year has been the best so far... I was just hoping "feeling it" and all the signs were enough. Trying to not lose faith and hope but for now, the tears are flowing ???? thanks for reading and encouragement..
