Help

:S Ok well here I go. I am almost two weeks late but all the test I’ve taken say no but two weeks ago I had some spotting n then nothing. I am a regular clock work with my cycle normally. For some reason I am late by more then just a couple of days. Now with my first pregnancy I did not find out untill blood work was done and with my second one I was like 2 months before the test came back positive. So I am not tottally new to this I am just wondering what I should Do.. Can u shine some light on this for me??? Please!!
