Had a pregnyl shot 6 days ago, what are the side effects?

Few side effects. The most common side effect is discomfort, irritation or redness at the injection site. Headache, irritability, restlessness, depression, tiredness and water retention have also been reported. You may get symptoms after ovulation such as pelvic cramping, bloating, or breast tenderness which occur after you release one or more eggs. Hyperstimulation of the ovaries is rare unless it's an ivf cycle.
