Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. The fact that your doctor has commented that your scan reports are good means that you are ovulating regularly. Endogest is a natural micronized progesterone preparation. After fertilization, progesterone is required to stabilize the pregnancy. This progesterone is released by Corpus luteum. If corpus luteum is weak, the pregnancy may not continue due to shortage of progesterone. Therefore you are given these pills. Moreover, Inj. hCG helps strengthening of corpus luteum. So it will be useful when the fertilization has taken place. If you miss the period, perform your pregnancy test on the overnight morning first urine sample, earlier the test may report false negative results. Alternatively you may perform Beta hCG test on the blood 10 days after the last unprotected intercourse. Now that the other medicines like Evion, Ebexid, M2 are not continued now, we need not discuss on them. Moreover, if you are ovulating naturally, you do not need these medicines. I hope this explains you about your medicines. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nishikant Shrotri
