Hi Dr. Purushottam welcomes you to HCM virtual clinic. I have gone through your query. I think I have understood your concern, I will try to suggest you the best possible treatment options. 1] If you have missed your periods , which is first sign suggesting that you might be pregnant. 2] urine pregnancy test if positive is usually quite reliable test, and you can assume that you are pregnant. 3] Vomiting, nausea, frequency of urination , heaviness in breasts, aversion to certain food items are some other symptoms of early pregnancy. As you are saying some women may get pimples on face due to hormonal changes. 4] I will suggest to confirm pregnancy by doing ultrasound test. I hope my answer helps you. Thanks.
