Can pregnancy occur if last period ended on 25th August?

Your ovulation model shows a 26-day cycle. The period between 26 and 28 of September is the best time for you to conceive around October 10-11. This is when you are most likely ovulating which means an egg is ready to meet sperm. Observing signs like increased vaginal discharge or gentle discomfort in your lower abdomen which is also called ovulation pain will help you in conceiving. Get the cycle record improved to track faulty periods, thus increasing the odds of successful fertilization.

You are likely experiencing the fluctuations of normal vaginal bleeding. Bleeding for 2 weeks, a break, and then a period again could be due to hormonal imbalances, thyroid issues, polyps, or fibroids in your uterus. The primary step here is to see your doctor who will examine you and order tests to find out the exact cause. Medication or minor procedures are the possible treatment options based on the diagnosis. 

It’s completely normal to feel anxious about this. When you don't get your period after having unprotected sex, it’s usually a cause for concern. Stress, hormonal imbalance, or pregnancy could be delaying it. Also, the fact that you took an emergency contraceptive might mess up your cycle. Just give it some time and you may see your menstrual flow soon. However, if there are other unusual symptoms or the delay persists consider taking a pregnancy test.

If a girl has sex before her expected period and then it comes on, she is likely not pregnant. However, some women may have light bleeding or spotting in the early weeks of pregnancy which can be mistaken for a period. If your girlfriend’s cycle was normal with the usual flow for 3-5 days then she is probably okay. Periods are sometimes irregular due to stress among other things so I wouldn’t worry too much about it unless there are other signs as well. 

Its normal if your period gets delayed by a few day, there's nothing to worry about.. Stress, adn hormonal chanegs can also lead to a delay in your periods.. Apart from that pregnancy is another factor and if you are concerned its important that you g et it checked.

A sonogram won't reveal if you had an abortion . It can detect pregnancy in general . Talk to your doctor if you have any concerns . 

Genetics might be one reason, or perhaps there are some constraints on growth. Sometimes this isn’t significant but follow-up with a healthcare professional is necessary for more assessment and observation. They will direct you accordingly so that the health and growth of your little one are right on track. 

It is quite usual to experience some discomfort during intercourse but prolonged pain should be checked out. Tightness and aching during intercourse could be a symptom of a medical problem such as vaginismus or a pelvic infection. I recommend you to visit to a gynecologist to get the right diagnosis and proper treatment.
