Trying to understand myself

TMI can someone please relate to me. I took birth control for 10 months to regulate myself my husband was deployed. He came back 1 month ago I got my period we started trying I've being tracking my CM and everything else. All of the sudden I have itching and inflammation no bad smell I have read everything. At first I thought what if an STD but he doesn't have anything the army does check ups, could I be back to my old self to be irregular, is it a yeast infection without a bad smell, has anyone else had the same problem. Can y'all help me please!
