Bloat or what?

Summer • 👼👧🤰
According to my ovulation date I am only 5 weeks 1 day. But I already have to wear a rubber band to keep my pants closed and even that is uncomfortable. Co-workers and my roommates are all saying I'm further along or having multiples. I don't have an apt until July 5th and whatever it is it is but could they be right or is it likely just bloating?
