Need suggestion. A friend. the details!

Dear Sir/Mam, I am 28 y/o unmarried female in sexual relationship with a friend. The details regarding the issue are as follows- My last date of periods was on 16 th Jan 2017. After missing my periods on next due date (around 16th Feb) I carried out a self pregnancy test with a test strip( preganews) and found myself to be pregnant. I then opted for MTP by swallowing one mifepristone tablet (on 20th feb) and two misoprostol tablets after 48 hours (22nd feb) followed by two more misoprostol tablets after 2 hours orally (as directed). Bleeding started within 24 hours and continued for around 4 days and ceased after that. Now, I am still having pain in my lower abdomen and would like to know what steps should be taken in order to confirm that the MTP has been done successfully. Also I have noticed a small patch on the left side of my inner thigh (near vagina) which is dry and having very little bumps on the edges. It is itchy. I would be grateful if I can know the reason and cure. Thanks.
