I am pregnant after two miscarriages. Can I take Progestogen and Aspirin injections?

Hello doctor,

I had two miscarriages; one was in the fourth week. While taking the scan, the sac was not found, and there was a two-week delay in growth. Another one for almost seven weeks and a two-week growth delay. Now, I am pregnant after six months of the second miscarriage. Now, I am in my third week. My doctor advised me to take injections of Progesterone and Aspirin, and one more substance was there, and I do not remember the name. I need to take the injection every day until the fifth month of pregnancy. The heartbeat and everything were fine from the second pregnancy till the sixth week. After the second miscarriage, I had a delay in my periods and took a scan 12 days after my period. My dominant follicle was smaller when compared to the regular size of 11.58. I would like to hear a second opinion on this. So please advise.
