irregular periods, hasn’t come yet-early and late, am i pregnant?

Anna

okay so i’ve been having irregular periods and my cycle has been an average of 14-21 days so I’ve had 4 periods since the middle of december. this was caused by sudden weight loss, i accidentally lost 25 pounds due to stress but i’m still healthy at 130 lbs.

my periods have NEVER been irregular before, always on the dot 28-30 days.

i’ve been having sex with my boyfriend only the week before my period and not during ovulation, we used protection and had been drinking.

my last period was 26 days ago, so late in terms of irregular periods, but early in terms of regular. i’ve been really careful to eat normally.

so am i pregnant? or is my cycle just becoming normal again?
