idk if i should worry about pregnancy

Generally, getting your period is a slam dunk sign that you're not pregnant. However, vaginal bleeding can accompany (or be a harbinger of) a miscarriage. Or (because I don't know your age, I'm throwing this out there), it could be a sign of perimenopause, when periods can become erratic.

Call your doctor and ask if anything I've written doesn't seem to apply. Also consider the last time you had sex. If the last time was before your period, and your periods aren't too regular and/or you're of an age where perimenopause is a very real possibility (40s, but there are women who start in their mid-30s. It varies), then that may be what it is.

Of course if you get bad abdominal pain, call your doctor.

Pregancy test will tell you. My exwife had bleeding all thru her pregnancy.

Only thing i have to say is, you can be pregnant while having you period.
If your areolas (the area around your nipples) have become darker or larger, you may be witnessing one of the first signs of pregnancy. This can happen as early as a week or two after conception. There's no need to be concerned—this change in appearance is just a normal result of pregnancy and isn't a cause for alarm.
I think you should go see a doctor.
