I have been on herceptin now for 3 months... infusion every 3 weeks. I have not had any chemo. My side effects are constant runny nose, acne after my infusions and severely irregular periods. My periods are coming every 2 to 3 weeks. Before I started herceptin I woud get my period every 28 days like clock work. I have asked my oncologist if the irregular/ more frequent periods were "normal" but he told me it was not a known side effect. Any other women experience this?

diagnosed at age 33 (Sept 2010)
DCIS and 3.0mm invasive tumor
ER-, PR-, Her2+++
opted for bi-lateral mast. with silicone implants
