Hello, Having missed your period, the first thing that you should now do is to confirm the pregnancy. You should also get a trans-vaginal sonogram and if pregnant, you can get the gestational age and also the location of the sac. Based on the findings, you can consult a specialist for a medical abortion as you have just missed a period. You will be given a proper prescription after preliminary investigations; the entire process, if properly planned and executed, takes one or two days. You may not need another D & C. Even if needed, if carefully performed, it will not affect future fertility. Please maintain genital hygiene. Hope this helps.
