unprotected sex not on birth control

Okay so, ive been on the depovera shot for about 2-3 years, cant remember..and my last shot was in december, im no longer on the shot anymore me and my boyfriend have sex unprotected and he does ejaculate inside of me. i dont know if its too early too tell and im just syking myself out but i looked up on a few websites that symptoms of pregnancy is breast tenderness wich i have VERY BADLY stomach cramps wich i have, but its weird i know the fealing of pms cramps and this is nothing like it i feal very bloated..but i know normally that your lower stomach gets hard. i havent gotten that yet. But like i said, i dont know if its too early too tell because when I think this could have happend would be tuesday, 4 days ago. BUT THEN im looking at websites with peoples opions quite like this one and people are saying you have too be ovulating too concieve!? and someone i dont know when i ovulate because i havent had a period in about the time that i have been on the shot and i still havent gotten one since ive been off.

can someone help me try too figure out a straight answer? i really want too know if its too early too tell if im pregnant and i would like someone who got their facts from a doctor too tell me if you have too be ovulating too concieve.

please get back too me a.s.a.p! thanks so much! :-)
