Germination problems with flax

I seeded my new flax seeds (as opposed to saved ones) on May 7.  Normally they germinate over 7 to 10 days, but 3 weeks later I had exactly 8 seedlings growing.  So I re-seeded the plot last week, May 28, and now 7 to 10 days later I have good germination.  However, since I sowed the seeds late, I do not know if the crop will ripen properly.  Only time will tell.
