gcse biology help!

Can someone please confirm whether this is correct and in the right order: (i find it so confusing)
The menstrual cycle:
FSH (pituitary) - matures egg, stimulates oestrogen
Oestrogen (ovaries) - builds up uterus lining, inhibits FSH and stimulates LH
LH (pituitary) - releases egg - day 14, inhibits oestrogen and stimulates progesterone
Progesterone (ovaries) - maintains the lining of the uterus, inhibits LH

FSH and LH don’t inhibit anything only progesterone and oestrogen do. And progesterone inhibits both FSH and LH

Do you do edexcel? For AQA there was literally no biology in that paper! It was all a bunch of nonsense
