Any hope?

Ever since I stopped using BC I’ve had pretty predictable symptoms about a week before AF: acne, cramps, and extremely sore breasts. This month I’ve had none of that. Used opk’s and had sex on, before, and a day after LH surge. AF is expected 4/10, negative pregnancy test today. This is only our third month TTC but I’ve been super tired and hungry for the past week, I’ve taken a nap every day. I ovulated late so maybe I just haven’t developed enough HCG to test positive yet? I had some cramping a couple of days ago.

Could I be pregnant? I just don’t want to get my hopes up yet. What do you guys think?
