Consti[ation i have no idea?

have had constipation since last friday or irregularity not to sure cause i am Still going to the bathroom i just feel that is not all coming out and still sometimes have the sensation to go to bathroom when i don't have to i have tried powdered fiber, prunes, prune juice, the smart plum prune juice, I've had Activa but only ate one yesterday, been eatting other yogurt, fiber cereals like rasian bran and shredded wheat, Metamucil powered this morning. i thought i felt like i was getting better yesterday my stomach was hurting less and didn't feel the urge to go all the time. Hopefully it will get better my dad's gf said just to give it time and it will work its way out. which i feel that is true i feel like if i go to the doctor he"ll just prescribe me laxatives which i have also taken. I guess i just gotta give it time and not think about it? not to sure just stressed and i need to stop stressing because i know that what constipation is also steamed from too. Anyone with suggestions would love to hear thank you. O by the way i am also on my period. But i never have gotten constipation near my period or on it. My dads gf was also saying its almost 7 years and ever 7 years ur body changes and stuff. I am also on birth control to if that helps but i highly doubt that is the problem. Also last thursday i ate really greasy foods which usually makes me go well it didn't and i think that is what has kept me blocked up. But yet i can still go i am not sure just so con fussed.
