I have had mid cycle spotting for the past two months. Last month it lasted 7 days, then I had 5 days blood free, then spotted for 6 days, then had a heavy period for days. Basically 13 days blood free in the past 2 months because I started mid cycle bleeding again yesterday. My doctor sid mid cycle bleeding was normal, ovulation, but it's more than spotting, bright red, and lasting 7 days with crazy irregular period bleeding (although period is coming at a regular time). Should I get a second opinion? what could this be?
