spotting 1 day after norethisterone (pcos)

[Geeholl]

Hi, i am new here.

my husband and i have been TTC for 15 months, i got diagnosed with PCOS in April 2019. after lots of issues with the NHS we decided to go private, i was given Norethisterone and metformin and clomid one AF makes an appearance.

i took my last norethisterone yesterday, today i am experiencing a slight bit of spotting/browny discharge (sorry for TMI)

Can anyone give me any advice as to if this normal?
