Is there still a chance of being pregnant this time

My husband and I have been TTC. lately it seems like my cycle is a bit longer, around 39 days. 
 We did the baby dance everyday. Literally, everyday in hopes of not missing our chance. 
 I feel like I've experienced some symptoms of early pregnancy that I didn't know about until I read about them. I've also had nausea, extremely tired, occasional pain in one side of my pelvic area, indigestion after anything I eat. My husband mentioned Chinese food and had me gagging. 
 I'm now a week before I get AF. I took a test this morning and had a BFN
I don't know whether to still have hope or if there's even a chance we are pregnant.
