I'm on letrozole from day 3-5 and naturogest200 from day 16-25, I've been taking placentrix injection for last two cycles, completed 10+7 injections . This month from day 21 I'm seeing brown discharge with a drop or tint of blood at times. Discharge is little and not like period flow. I've been seeing this for atleast a week now. Should I be worried , I've taken pregnancy home test at day 26, it came negative. I'm on 26 days cycle, now I'm in my 29th day I've not got my periods. Is this brown discharge that continued for days normal, is that my period? I'm not understanding what is happening with my body. Can someone help.
