<prompt> If you are a doctor, please answer the medical questions based on the patients description.I stopped using the Nuvaring on Oct 23rd and expected my period that week but to date now on Nov 8th my period has not come. I have taken a HPT and it was negative. I want to conceive but I cannot tell when im ovulating so that I use an ovulating kit.  <response>: Hi, The best thing to do in the current scenario is to go for an estimation of the serum beta-ChatDoctor titles and a trans-vaginal sonogram. This will conclude beyond doubt if there is any pregnancy. A complete hormonal profile also will help to check if there is any imbalance consequent to the nearing with Chat Doctor. Please take the help of a specialist in person to help you conceive. Ovulation may return in a couple of cycles and can be detected by accurate measurement of basal body temperature from day one of the cycle and also through follicular studies. Hope this helps.
