The wait.

So I am 25 an I am 14 days past my period date. The past year my periods have been pretty much on time maybe a day late. I have taken 4 ptest an all are negative but 1 had a very very faint line I'm assuming I let it sit to long. I want to test again so bad but trying to not waist the money.

•My nipples are sensitive

•I've randomly woken up partially feeling sick

•Very very light lower pelvic discomfort

•A week before my period was supposed to come I had some brown discharge

•I feel like I have to pee all the time but I dont pee alot every single time

•no period

• no period symptoms

Help! Why is this happening?
