The presence of lower abdominal pain during ovulation is known as mid-stage pain, which is mainly due to the painful sensation produced by the egg expelling from the ovary, which is one of the signs of ovulation. It usually occurs 2-3 hours before ovulation and the pain symptoms are not very pronounced, mainly manifesting as cramps and other transient relief. If the pain symptoms are obvious, combined with abdominal distension, back pain, lumbar swelling and abnormal discharge, further examination is needed to rule out appendicitis or pelvic inflammatory manifestations. Ovulation pain is followed by follicular rupture about 24-48 hours later, resulting in the release of the egg. If you have intercourse during ovulation, the chances of conception are relatively high when the egg is combined with sperm. The main symptoms of ovulation are decreased appetite, high energy, or high sex drive, but resistance will be relatively lower, and most women have no special symptoms during ovulation. Due to the high level of estrogen and progesterone during ovulation, the leukorrhea will increase significantly and become clear and watery, or it will be stretched, usually lasting 2 to 3 days. In short, if you are preparing for pregnancy, you should arrange intercourse during ovulation. If ovulation is irregular, you can choose ultrasound, ovulation test paper and basal body temperature to effectively monitor the development of follicles to improve the chances of conception. Once ovulation pain occurs, you need to schedule intercourse.
