My term is every 3 month, how to regulate it?
Answers: If you are just having a interval every three months and want to get pregnant, you really should walk to a OBGYN or to a reproductive specialist. They will probably do bloodwork to check your hormone levels to see why you are lone getting a period every 3 months. You may not be ovulating, and they may put you on a low plane fertility drug to help induce ovulation (Clomid usually). It would also be influential to know why you may have miscarried since (if you went to the doctor after the miscarriage..it could be low level of progesterone that caused to miscarriage or other things). That would be completely important as ably, to make sure that when you get pregnant, it doesn't end contained by another miscarriage.
If you weren't looking at becoming pregnant, they would most likely prescribe birth control pills so you hold a period monthly.
Good luck!
If you're with the sole purpose having a length once every three months, you should seriously consider speaking to a Health Care Professional.
There could be something else going on, but the most likely first step they would clutch would be to put you on birth control pills to get your time of year on to a regular schedule.
