Anyone can become pregnant immediately following their menstruation. According to a 2018 study, a healthy person's cycle might vary by up to 9 days every year. As a result, even someone who generally ovulates around day 17 or 18 may ovulate significantly sooner on occasion. Most health care providers will tell you that you cannot get pregnant if you have not had your period yet, but if that statement was true, then no one could ever get pregnant. The fact is that most women of child-bearing age have periods about 21 days out of 30 and only around 5% of women report having their period more than 7 days past its normal date. So although it is possible for a woman to get pregnant as early as 6 days after her last flow, this occurs only around 5% of the time. Most women know within a few days if they are pregnant or not and if they are experiencing some sort of pain or discomfort they should consult with their doctor. Some common symptoms of pregnancy include: feeling tired, nausea, vomiting, breast tenderness, increased blood pressure and heart rate, headaches, depression, and weight gain. Many women also report having their period earlier than usual or missing their period all together. While many of these symptoms can be caused by other conditions, it is important to note that pregnancies tend to be easier to detect if you are looking for them.
