Spotting?

My husband and I have been TTC for about a month. My periods have always been very regular; I've never missed one and my cycle is always about 29 days. I've also been off BC for over 3 years (my body hated it but that's a different story). My last period began on Jan 23rd and ended on Jan 27th. Then yesterday (feb 2nd) it was like my period started all over again. This has never happened to me before and it's freaking me out. Is this normal? Have any of y'all experienced anything like this? I have an appointment with my gynocologist but it's not until feb 10.
