Ask me if I'm pregnant or not!

Hi, Dr. D, please ask me if I am pregnant or not: my last menstrual period came on September 10 and so far there has not been anything in my accounts yet if I have been pregnant I am 5 weeks old and I feel a tremor in my belly and when I put the hand I felt a ball I may be pregnant, but also when I think that my period is late I feel like a colic; answer me please ... thank you in advance!
