Spotting

My period came back 4 months after giving birth to my son.  It has moved up by at least 2 days every month since it started.  My son is now 13 months old & I am still breastfeeding him.  I have never spotted between periods before until this month.  My period started on the 9th of Nov. and was only 3 days long.  I started just light brown spotting yesterday & still into today.  Could this be hormonal or an infection of some sort.  I already started 2 days ago with the stringy, egg white like mucus.  So could I just be ovulating?    I'm just concerned about the spotting.

Its pretty unlikely its an infection.  More then likely it is hormonal.  It can be a symptom of low progesterone, or could simply be your body regulating itself again.  If you are concerned, mention it to your Dr., but mid cycle spotting is really not all that uncommon.  Good luck to you!!
