Negative Test

I convinced myself this was our month. That my severe allergy symptoms, moodiness, pelvic pain on my left side (especially while sleeping, well trying to sleep) and lack of appetite were signs I was pregnant. According to Glow, AF is due today. Tested this morning because I turn into a crazy person during this time and it was negative. My husband and I have been trying for a year and he's really pushing for me to make an appointment with the doctor to see what the issue is. I feel like I want to give it more time to happen on its own. Could it be possible to get a BFP still if AF doesn't show? Any advice is so appreciated.
