Basal body temperature
Basal body temperature charting is very helpful for women who are not sure if they are ovulating. Charting gives women the best chance to conceive by maximizing the sperm present when the egg is released. Basal body temperature is temperature of a person's body taken first thing in the morning after several hours of sleep and before any activity, including getting out of bed or talking; often charted to determine the time of ovulation.
This is what you need to do, take your temperature first thing in the morning and write it on a chart. Your goal is to see a change of a least 0.4 degrees fahrenheit after ovulation. Which means showing low temperatures before ovulation in the follicular phase and higher ones after ovulation in the luteal phase. For most women, 96 to 98 degrees is normal before ovulation and 97 to to 99 degrees after ovulation.
Some people will not have a rise in temperature when they ovulate. The change in temperature can happen two to three days after ovulation. By then it's a little too late to try to have sex to achieve pregnancy.
You should start to take multi vitamins, be sure it contains folic acid. Stop smoking, you do not need to smoke while you are pregnant so go ahead and quit now. Stay away from alcohol. Alcohol is not good for you or your baby. Eat enough calories. Being underweight or eating a low calories diet can throw off your monthly cycle. Get in the habit of eating healthy, wholesome foods and stop eating sweets. This will help you get pregnant.
Do not use lubes
A lot of over the counter lubes are not sperm friendly, they actually hurt or kill the mobility of sperm and should not be used while you are trying to get pregnant. One lube that is not harmful is vegetable oil.
