My period has been very unusual and very long lasting this month. Today is Saturday and I started on Monday LAST week so it has been almost 2 weeks. It started off very light and showed up more brown than red (how it usually is when i am finishing). However, 2 days it became very heavy and very red (like how it is at the beginning of my period), and it is currently like that. I am worried there is a medical issue or there's anything to do with pregnancy as I am sexually active.
