The best time to have an abortion is within 49 days of pregnancy. The size of the gestational sac is usually larger than 1 cm around 49 days of pregnancy, so the chances of missed aspiration or scraping are reduced during the aspiration or scraping procedure. Normally, the time of pregnancy is counted backwards from the beginning of the last menstrual period, if the first day of the last menstrual period is January 1, then the 49th day of pregnancy is around the 20th day of February. If you choose to have an abortion, you must undergo a gynecological ultrasound examination before having an abortion to see the size of the gestational sac, determine the time of conception, determine exactly when you can operate, and rule out the possibility of ectopic pregnancy, which will help a lot in the safety of the abortion procedure. In addition, after the abortion surgery, it is recommended that patients must pay attention to the post-operative recovery and apply medicines such as motherwort to promote contraction and recovery of the uterus.
