Hi.
I have a few options for you but you need to really dive deep into the topic and read everything about natural contraception.
Symptothermal contraceptive method / symptothermal NFP -> You need to get to know your cycle and measure the body temperature and observe your cervix mucus every day. There are apps you can use to help you oversee your cycle.
Herbal contraception:
> Wild Carrot Seeds (Daucus carota). Only needs to be taken during the fertile days, about 7-9 days, depending on how long your cycle is. Can be ingested as whole seeds, tincture or tea - all methods work. (for this method you need to get to know your cycle. When your cervic mucus is very slippery and transparent you are at the most fertile day of the month, which is around the 14th or 17th or your cycle).
> Mexican Wild Yam Root. 2000mg need to be taken everyday. The contraceptive action starts 3 months after.
> Embelia (Embelia Ribes / Vidanga). Taken from 5th day of the last menstrual period for a period of 15 days in a daily dose schedule of 1g (2 tablets, รก 500mg) at bedtime.
Wild carrot:
"Thee earliest reference dates back to the 4th or 5th century B.C., in a book written by Hippocrates. He described the use of wild carrot seeds as an oral contraceptive or abortifacient (depending on the dosage). The reference by Hippocrates appears to be the oldest reference to the anti-fertility activity of Daucus Carota seed."

The seeds of vidanga (embelia) plants destroy sperms. The berry-like fruits contain a chemical compound known as embelin. This substance has exhibited notable post-coital anti-fertility and anti-implantation activities.

Studies show the contraceptive effects of wild carrot and also embelia work very well.
