TTC for 8 months now and normally my periods are between 30-32 days. It's always been like that. This month my period came a week early and it's an extremely heavy flow. Like I have a super absorbent tampon in for just over an hour and it bleed through. Could I have had an extremely early miscarriage? Should I give my doctor a call? Any one ever experienced this before? Or am I just over reacting about it....
