Mild symptoms, firsy pregnancy.

Obviously i know having symptoms your first trimester is normal. But the only symptoms i have had was mild cramping and stomache pains, sore breasts, and peeing more than i should. Oh and a mild headache that felt like a hangover this morning. Should i have more at week 4-5? We just found out 2 days ago i was pregnant but it is my first pregnancy and am worrying because, his doctor told him his chances were slim to even concieve. I go to the doctor friday to confirm but 3 positive tests later youd think something is there. Maybe everyones symptoms are different?
