Hello and thanks for the query, I would first explain to you about the female reproduction and then some ways to recognize when is the best chance of getting pregnant. The female is designed in such a way that every month on about the 14th day of a regular 28 days cycle, one female egg called ovum is released from the ovary and it goes to the tube and gets fertilized by a male sperm if there has been a recent sexual contact. So if sexual contact occurs during ovulation then only pregnancy will result. Having contact on all other days of the month will not lead to pregnancy. The day of ovulation varies and it may occur on any day from day 10-20 from the first day of the menses. hence this is called the fertile period. So for having a maximum chance of getting pregnant a healthy female egg, an open female genital tract [ that is no block in tubes, cervix and a normal uterus and its lining] are important. Ovulation can be detected by measuring the body temperature every day before getting up from bed using a special thermometer called a BBT thermometer. After ovulation the female body temperature increases by about 0.5 to 1 degree. Another way is to check the cervical mucus. the mucus is thin and watery during ovulation period. Special ovulation detecting kits and sonography can also be used to detect it. As of now I recommend you try to keep alternate day sexual contact between day 10-20 of the cycle for 6 months. If there is no success, visit an infertility specialist to look for any cause for not getting pregnant. Also start taking b complex and folic acid tablets if you are planning pregnancy as they help prevent birth defects in the baby. Hope this was helpful.
