Ladies Help !!

Well Im scared/confused and a bit concerned about this:

I have an irregular period i guess because it is ALWAYS late and its crazy, pain cramps and everything.

I had sex almost 2 weeks ago with my man and he ejaculated in me since im not on birth control we went and bought emergency contraceptive.

Well like 4 days after that it happened again and i bought another emergency contraceptive from a different brand as well and took it because i was scared i mean we are not ready for a child and since we always use condoms i am not on birth control, so yeah i took 2 emergency pills in less than one week, awful pain after that and now 2 weeks later i got my period and it hurts so bad and it is early im supposed to get it like in one week, and im never early ... What should i do ?!!!
