Pregnancy Info HOME

I have been on the pill for almost a year now. I just had my period March 3-7 and then started my new pack on the 7th. I had unprotected s_x with my boyfriend on March 14th. I have not taken my pills since March 15th. I started my period again March 17th and it has been heavier then it has ever been and with almost quarter size clots every time I visit the bathroom. I have been on my period now for 7 days. I do not know what is going on. I'm not sure if I could be pregnant or if I am just having my period again because I stopped taking my pills. Any information would be helpful, thanks!
