Gained weight

Recently I have gained weight. I should be losing but you all know how hard that is so anyway I gained. In the past my periods have been kind of unpredictable but I got then under control after losing 10lbs and tracking my bbt. This month I got sick right before ovulation so I stopped temping for the rest of the cycle. Now I am late for my period a few days and I have no way of knowing if I gained weight cause I'm pregnant or if I didn't ovulate because of the weight gain. Ugh I hate not knowing.
