Why is my period schedule changing after marriage?

Abdominal pain, lower back discomfort, and irre­gular discharge during pregnancy raise conce­rns. Such symptoms may signal potential infections or problems. Promptly contacting he­althcare providers proves crucial. The­y'll likely evaluate you to pinpoint symptom cause­s. Appropriate treatments aim to safe­guard you and your baby's well-being. 

If you used a condom that didn't break or leak and you had sex on the 8th day of your cycle, there is a low chance of getting pregnant. It's usually difficult to conceive at such times in the menstrual calendar. However, remember that no contraceptive is entirely foolproof although using it correctly reduces the risk significantly. If there are any unusual signs or symptoms, it may be a good idea to do a pregnancy test to be sure.

Painful headaches, vomiting, and pale face during periods - common. Vitamins and folic acid may not work. Consult a doctor immediately. 

By assuming a standard ovulation cycle of 28 days, ovulation occurs at the time of the next period which is 14 days prior to the period. Thus, your last period began on August 20th, hence you are likely to ovulate on or around September 3rd. Some indications of ovulation are differences in the thickness of cervical mucus, slight abdominal pain, and a rise in basal body temperature. You can also use ovulation predictor kits to check for ovulation.
