Signs of Ovulation
- A slight rise in basal body temperature, typically 1/2 to 1 degree, measured by a thermometer
- Higher levels of LH, luteinizing hormone, measured on a home urine test
- Cervical mucus, or vaginal discharge, may appear clearer, thinner, and stretchy
- Tender breasts
- Abdominal bloating
- Light spotting
- Slight pain or ache on one side of the abdomen
- Have Sex Often: Your odds of getting pregnant are best when you have sex 1 to 2 days before you ovulate. But cycles vary in length, and some women are irregular or have miscalculated their cycle. Sperm can survive in a woman's body for up to 5 days. To hedge your bet, have sex frequently starting 3 days before ovulation and continuing for 2 to 3 days after you think you've ovulated.
- Lie Low After Sex: Give sperm a chance to swim upstream before going to the bathroom. Stay in bed for at least a few minutes after intercourse.
- Create a Sperm-Friendly Environment: Avoid vaginal sprays, scented tampons, artificial lubricants, and douching. They can alter the normal acidity of the vagina.
- Know When You Ovulate: Chart your basal body temperature and your cervical mucus. You might also use an over-the-counter ovulation predictor kit (OPK) to check for hormonal changes in your urine before ovulation.
- Maintain a Healthy Weight: Studies show that weighing too little — or weighing too much — can disrupt ovulation and may also affect production of key reproductive hormones. A healthy BMI is between 18.5 and 24.9.
