12dpo according to glow

So my husband and I just recently came off birth control and are TTC. I’m on my 3rd cycle off birth control so we’re still just trying to enjoy this journey and we’re not tracking anything and we’re just having fun doing this. Well.. normally I know my period is coming because of extreme moodiness and breast tenderness that occurs starting the week before.. (my periods have been normal and on time since coming off the pill, I was on it for 6 years).. well I’m 3 days away from my period and I have NO signs of AF and since yesterday evening I’ve been getting random cramps/twinges in my lower abdomen... could this mean anything? Are these twinges possible implantation? I’m really hopeful but at the same time I have no “pregnancy symptoms”
