Should I be concerned?

alright so... I got put on the pill a few months back. they were hoping itd regulate my periods, thinking I just had a hormonal inbalance. well...

this past round it was late... like... by a week...

the period itself only lasted 4 days and was highly irregular compared to past ones.

well. I'm still feeling bloated and crampy or like ive put on weight at the tummy... even my belt for my work uniform seems to press into my tummy more and cause me to hurt...

maybe I'm just paranoid because I missed a day of my pill (no I didnt have sex or anything that day nor the day before or after)... but should I be worried??? I'm just... feeling off... he'll I drank 4 glasses of strawberry milk yesterday as a craving when normally I don't have a taste for milk at all...???
