What are the chances that i could be pregnant?

i had all preg symptoms up until my period due date. the first day of my cycle was very VERY lite, which is quite uncommon for me. the next day was like a reg cycle and id lasted a reg amount of time. now, nearly a week after i still feel some preg symptoms. like i just dont feel me normal self. im also experiencing some abnormal hair loss! its shedding quite alot, but i have not felt stress lately. my relationship with fiance is at the best point it has ever been! please share your advice/opinion with me! lastly, the number one reason i thought i was preggo was enlargement which they are Still huge. im super confused and thrown off my that period i had but to nervous to take a test! ugh dont you hate the time while ttc you mind seems to be playing tricks on you, ruthlessly =/
