Cramping on day 18 🤔

Breanna
Hello TTC ladies . I have been recently being TTC for 8 months now and so far nothing . My cycle days are 25/26 days every month and I normally start cramping 4-3 days before period . I also have a cyst on my right ovary. During this cycle I've was supposed to ovulalate on cycle day 11 and I've baby danced about 7 days during my fertile week. And I also ate pineapple code But today on cycle day 18 I started having cramps and lower abdominal pain on my left side which I never have pain on . I don't think I should be cramping as early as 7 days before my period . What do you think it could be ? Baby dust to all of you . 👶🏽💛
