We started ttc exactly one year ago. At the beginning we did all the checks at the doctor and etc. They found out my prolactin was a bit high and during the year while we monitored it it just went up and down. Now in October I finally did an MRI to understand if this is related to stress or smth worse. Thanks God all was good and after that based on my latest analysis, the prolactin levels went down which made us really happy. My cycles are very stable (26-28days). During the last couple of months I did tracked my ovulation. Some months it was right at the spot (CD14/15).. some months. did not had one. This month, just after 2 days my period ended, my breasts became sore and tender which was never the case before ( usually during ovulation, PMS or during period). I was expecting to ovulate, but nothing, getting only negative results till today. I started to test my ovulation on CD9 and now I am day CD16 where I should have ovulated by now. On D13 , I noticed in my underwear some strange brown discharge which I never ever had before.Nothing afterwards.My boobs hurt until now... 
Either I am going crazy but I am thinking what if I ovulated right after my period which is wayyyy earlier than normal and the brown discharge was actually implantation bleeding? 
Would really appreciate if someone can share if they had a similar experience.
