Hi, I am 4 weeks pregnant and I want to go through an abortion, I am using the unwanted kit which contains mifepristone and misoprostol tablets

I started the course by taking the mifepristone 200mg and after 48 hours took 2 tablets of 200 my each misoprostol vaginally.

I have been experiencing heavy bleeding, do I have to complete the course and take the remaining two misoprostol tablets? If yes, can I take them orally?
