[/INST] Hello, I have gone through the query and understood your concern. If you have always been regular with your cycles and missed this one, you should perform a home pregnancy test with a fresh early morning sample 3-7 days after the missed period. Else, you can also go for the estimation of the serum beta-ChatDoctor titles for an earlier and better clarification. If positive, please see a specialist for further management. After a trans-vaginal sonogram to locate the gestation sac, if you do not wish to retain the pregnancy, you may be induced to have an abortion. Hope this helps. </s>
