Need a woman’s perspective

So my wife and I have been trying for our first baby for 4years she was diagnosed with PCOS 2years of us trying so by year 3 they finally decided to refer us to a fertility clinic we finally got an appointment feb 1st and they give her metformin clomid and she still hasn’t started them I have asked her when she will start and she always says Monday then Monday comes then it’s il start next Monday I asked if she still wanted this she says yes as badly as you do but why won’t she start them she said she’s just scared of the side effects but I don’t know it’s got to be something else

What you ladies think?
