What Are The Side Effects Of Fertigyn?

I HAD PREVIOUS MISCARRIAGE 4 YRS BACK AT 12 WEEKS ? UNKNOWN CAUSE . I AM 31 YRS OLD NOW AND EXPECTING MY 2ND CHILD . 5 WEEKS PREGNANT BY NATURAL MEANS THOUGH MY GYNAE DID SUSPECT PCOS AND PUT ME ON METFORMIN FOR THIS . SHE HAS ASKED ME TO START FORTIGYN INJ AND PROGESTERON. I AM NOT SURE IF FORTIGYN CAN CAUSE SIDE EFFECTS INCLUDING OVARION HYPERSTIMULATION SYNDROME AT THIS STAGE? SHOULD I TAKE IT OR TAKE A SECOND OPIONION REGARDING THIS
