Regarding MTP. Please kindly tell).

My partner is approximately 1 month pregnant. But we don't want a child right now because of unstable conditions. On 23rd Jan she had taken MTP kit(mifepriestone and misopristole tablet contains 5 tablets). On 23rd Jan night she had taken the big tablet and on 24th night she had taken 2 small tablet and on 25th she had taken 2 small tablet. But blood doesn't comes out. After few days she experienced some clotting and after that day nothing happens. Then yesterday when we checked pregnancy status, it showed positive. And today we have done ultrasound, that also gives a positive result with a normal pregnancy. So my question is that, can she take another MTP kit tablets or any other medicine (if yes, then which medicine please kindly tell).
