NEED ADVICE/HELP ASAP

Allison
How is it possible to have my period for 9 days and it stil hasn't ended?? It's barely there and been that way the whole time. Except one time when I whipped it was a bit more!! Should I go on BC for a month or two? I've been TTC for 16 months and I don't want to mess up my chances of getting pregnant. Any advice??
