It is definitely not advisable to take the kit frequently. The bleeding that you have mentioned may be very heavy and prolonged in some cases requiring emergency medical services. Also the periods will be disturbed for the coming months. And if the pregnancy is not terminated, then fetal malformations can occur. Before administration of mtp kit, uterine pregnancy has to be confirmed by an ultrasonography. Extrauterine pregnancy like tubal pregnancy can cause a lot of problems. When mtp kit is administered, accessibility to an emergency service should be available instantly in case of any emergencies arising out of complications. Lastly, it is better to go for any method of contraception like barrier methods or hormonal methods rather than frequent administration of map kits as they have increased risk of complications. Hope this helps. Thanks.
