No sign of baby.... :(

I'm feeling so disheartened :( we have been TTC for so long now and trying extra hard the last few months, tracking my ovulation and having sex every other day, but it's now 5 days until my expected period and I have No sign of any pregnancy symptoms and really just feeling like I should give up :( :( the worst part is all my friends are announcing their pregnancies or having babies and all I can think about is how that is just not happening for me :(
