Why would your left ovary be swollen during pregnancy?

A swollen left ovary during pregnancy could be due to several factors, including the presence of ovarian cysts, which are common and often benign during pregnancy. Hormonal changes can also lead to increased blood flow and swelling in the ovaries. In some cases, it may indicate a more serious condition, such as an ectopic pregnancy or ovarian torsion, so it's important to consult a healthcare provider for proper evaluation and management.
