Husband came home from deployment

Cortney
Okay so before husband left we were TTC- husband left end of Jan, he returned home June 1. 
Which June 1 I started my period. 
Normal cycle. 
For the past few days I have been super moody and we are also TTC again, after "baby dancing" I have a slight pink discharge. 
Today I have been super sleepy and my head has hurt. 
Used the restroom to find I was bleeding once again, more like a medium flow. No cramps. 
My apps state that I should be ovulating starting today. 
I have always had a cycle of 31 or more days. 
What do you ladies think is going on??
