12dpo BFN. Still hope?

Im 12dpo and took a test this morning-BFN. AF is due in two days. I've been nauseous for the last 5 days and barely able to eat half of the things I normally like. Is it still possible to get a BFP or should I just give up hope for this month? Its our first month trying so I wasn't expecting it to happen immediately but still disappointing.

Update: AF showed two days later. Trying again this month.
