Possible implantation????? Please help!!!

I have pcos and my husband and I have been trying for three years!! This year we decided to take a break... I finally got my period March 30-April 6 after 120 some days of not having it.. well on the 14-15th I had brown discharge thought nothing of it really.. then my husband and I tried to have sex last night and I swear my vagina was closed.. but then I woke up this morning and again I have brown discharge... has anyone ever have this before??! Could this be a good thing??? I pray it’s finally my turn!!!!
