?? Not sure what’s going on....

My husband & I have been TTC for 22 months. I have seen my gp, and was referred to a gynecologist/obstetrician who did blood work, ultrasounds & and an HSG. She referred us to a fertility clinic. Our first appointment is next Thursday.

My periods have always been regular 28-30 day cycle. Very heavy, and painful & usual last 6-7 days. I am just wondering if anyone has experienced bleeding between periods. I am CD 18 and today am bleeding. Not a lot, and no real other symptoms—bright red. Should I be concerned? This has never happened to me before.
