first you have to check urine for pregnancy. the pregnancy test will be positive from the next day after the missed periods. so you should get two lines if pregnant now. once confirmed have a scan to confirm the location of pregnancy. mtp (medical termination of pregnancy) kit will dislodge the pregnancy if it is intrauterine. so its location has to be confirmed whether inside uterus or not. unfortunately if it is in the tube then management is different. once intrauterine pregnancy is confirmed then you can use mtp kit any day sequentially. it is most effective up to 12 weeks of pregnancy earlier lesser the bleeding. you have a lot of time so do not be in a hurry. for further information consult an obstetrician and gynaecologist online --> <link>
shall i use mtp kit as my last period was before 43 days?
