Is this opk positive ????

Lami

Been testing two or three times a day this week and I think this is the darkest it's been . Glow said today is my most fertile day but still another day or two of my fertile window. My days said yesterday was my ovulation day and peak fertile day. Ovia said I should ovulate today but has adjusted till tomorrow because of this positive LH surge. Swollen breast and sensitive nipples last night and light cramps this morning . Should be day 19 of my cycle .

What do you ladies think ??

Took these over the week (picture upside down fyi)
