2ww period ...

Janice.
Hi there!
We did a fresh embryo transfer on Jan 28.  Three day 3 embryos.  Now the waiting period.  Blood work scheduled for Feb 12.  Have done 3 hpt - all negative.  Mixed emotions....in reading some says it's too early to tell...others say it should be positive if successful. Always hard...miscarried last year and really was hopeful this time. Others experience?
