Question

what is the first stage of mestruation​

Answer 1

                                                Follicular phase

          The follicular phase starts on the first day of your period (so there is some overlap with the menstrual phase) and ends when you ovulate. It starts when the hypothalamus sends a signal to your pituitary gland to release follicle-stimulating hormone (FSH).

Answer 2

Explanation:

● Follicular Phase

• The follicular phase starts on the first day of menstruation and ends with ovulation. 
• Prompted by the hypothalamus, the pituitary gland releases follicle stimulating hormone (FSH). 
• FSH hormone stimulates the ovary to produce around five to 20 follicles (tiny nodules or cysts), which bead on the surface.
