How early do you take pregnancy test??

MKA
Hi ladies. I'm new to the glow community. I had a false positive In Nov. 2015 and chemical pregnancy in April 2015 (both were surprises). And my husband (27) and I (24) are now TTC. But my question is, how early you do test? And what EPT do you recommend? I'm approx 7 days Post ovulation and I had a negative preg test today. (Clear blue digital)
