Increased foaming during ovulation is a very common phenomenon, which is a sign that the body is expelling harmful substances. During ovulation, a woman's nasal cavity and throat will secrete a large amount of foam. These foams contain some proteins and bacteria, so they will float in the air.

Increased foaming during ovulation is not a bad thing. Although these foams contain some bacteria and proteins, this does not mean that the body will be harmed. On the contrary, this kind of foam can help women better filter harmful substances in the air and protect their health.

In addition, increased foaming during ovulation can also help women predict future egg quality. If a woman often secretes a lot of foam in her nasal cavity and throat, her egg quality will be better and she will be more likely to get pregnant.

While foaming during ovulation is normal, that doesn't mean women need to take steps to avoid it. Women can reduce the risk of infection by maintaining good living habits, such as washing hands frequently, wearing masks, and maintaining social distance.
