CD39, no AF, is there hope for BFP?

Period cycles are anywhere from 28-32 days on average. I have had the occasional longer cycle from time to time. I’m on CD39...on 11/4, I had sharp pains in my abdomen (thought for sure AF was on her way)...no period. I have felt nauseous (and even throw up a few times in the last week)...constipated/diarrhea. Well then on CD37-CD38 I had a few spots of blood when wiping (TMI) but that’s all it was. It was literally like a drop of blood each time (maybe 3-4 times total) and now nothing...not a single sign of blood. Could I be pregnant? I don’t want to get my hopes up because we have been TTC for 6 years. Anybody have a similar story?
