My endometrial thickness is 5-6 mm, would this affect me to concieve? I want to know am I fertile or no. What are chances of me getting pregnant

Endometrium. Conceiving ability doesn't correlate with the endometrium thickness. For you, it's normal, although, it varies throughout your cycle, being thin in the folicular phase (the beginning of cycle) and being thickest at the end of it right before the period.
