s a possibility you could be pregnant, if your sexually active, but there could be a lot of different factors.. Stress/depression can delay your
period and def make it seem not so normal (regarding the flow). If your not in any pain, or feeling strange *(except worrying) then I'm sure it's fine. Mother nature is a strange being! Take some pregnancy test and call or visit your gyn and express your concerns. I'm sure everything is fine!
