I didn't want to bump 2 different threads for my updates, so here they are:
loss/tests worry - Pretty sure the faint line on the pregnancy was just the last little bit of hormone in my system, took another test and no more faint line. Got my results and hormones measured at 9 last Friday, so no more weekly blood tests, yay! Now waiting for AF to arrive so we can try again.
parent/teacher conference - Turned out to be nothing to worry about, just a routine thing. DS is on-track on all his developmental milestones!
