Uncertain EDC: you should see your OB/Fd to have a sonogram for dating your pregnancy then you can follow accordingly for your testing in order. Good luck

US Needed: You should only get a triple marker test after you KNOW for sure how far along you are and the best way is to correlate your LMP with your ultrasound. If you do not know how far along you are, the lab will not be able to tell you whether or not you have a normal or abnormal result because it depends on the age of the pregnancy. Get an US as soon as you can.
