i am late on my period.. i took to test one the day before my period was due and one a week after and both were negative.. so i thought i wasnt but now i realized i am 20 days late and i am experincing sore beyond sore nipples and just aint really feeling my self( if that makes any sense).. can i still be??.. could my hcg level have been to low to be detected in my urine??. i made a appointment t get blood work done..for onday .. but i like other peoples thought and ideas.. please leave your thought.and an other thing i am not stressed ..lool..
