Ayurveda has no method to stop pregnancy after sex. Take an emergency contraceptive pill (within 72 hours). Your pregnancy chance is low but possible Don’t use home remedies — not safe.
I strongly recommend consulting a gynecologist immediately for a reliable clinical solution. In the Ayurvedic tradition, preventing conception after unprotected intercourse involves using herbs that are believed to alter the environment of the uterus or act as “Artav-shodhak” (purifiers of the reproductive system). Ayurveda views conception as a result of the healthy union of Shukra (sperm), Artava (ovum), and Ambu (proper nutritional environment). To prevent pregnancy, the goal is to introduce “Vamana” or “Lekhana” (scraping) qualities that prevent the zygote from implanting. Ayurvedic remedies are not scientifically proven “emergency contraceptives.” Unlike modern morning-after pills, Ayurvedic herbs do not have a guaranteed success rate in preventing pregnancy after the act has occurred. If you are within the 72-hour window since intercourse, the most reliable method to prevent pregnancy is an emergency contraceptive pill (like i-Pill or Unwanted-72) or an IUD insertion by a gynecologist. Since you mentioned your period ended on April 6th, you may be entering your fertile window, making the risk of pregnancy higher. Traditional Remedy: A decoction made from the root of the Hibiscus plant (Japa Kusuma) or Carrot Seeds (Gajjar Beej) is traditionally used to prevent implantation.
As you mentioned your periods ended on 6th april (4th/5th day of mensis) amd you had unprotected sex today 9 th April (8th/9th) day of pregnancy there is no chnce of getting pregnant. In case of norma menstural cycle the days 11-21 days from the start of your mensis are the fertile days and rest all days you are not fertile meaning you donot get pregnant on these days. Regarding contracepyion in ayurveds ther is no such mentioned contraception so you will have to go for some kind of unwanted 72 and take it within 72 hours if you feel like you may have chances of pregnancy.
