Welcome to HealthcareMagic forum.
Have you restarted microgynon
pills after stopping it midcycle in April?
is ruled out with 2 home pregnancy tests, then the likely cause for absent period is hormonal imbalance.
You need to visit a gynecologist near your locality now. A detailed clinical examination along with investigations such as ultrasound
scan and blood test
may be done. Birth pills such as progesterone
only pill can be given for 2-5 days will be started and stopped abruptly. I expect your periods to resume after cessation of these pills.
In the rarest circumstances if period do not resume with birth pills, you are likely to be advised dilatation and curettage to mechanically induce bleeding.
Hope this answers your query.
Wish you good health
