Before your 1st beta I'm assuming? (not just the frequent b/w when you're on stims?) I had brown spotting which was unusual for me before the actual beta and was actually pg. Best of luck.
Every one of the girls on my local board that did IVF bled before beta bloodwork and ended up pregnant with twins. So it is very normal to have some bleeding, even bright red. Have you POAS? GL
