No af no bfp

Was supposed to start my period Saturday. This is my first month off BC so I’m not sure if my body is just trying to regulate. Took 2 pregnancy tests Tuesday 12/19 and Friday 12/22, both were negative. Thought i had symptoms last week and week before (acid reflux, sore nipples, and lower abdominal cramps) but nothing now. We had sex 2 times before glow estimates my ovulation so pregnancy is possible, but i didn’t do OPKS or BBT so no idea when i actually ovulated. When did you all get your first period after getting off BC? I was regular before the pill
