Can you get pcos after having children? i had my kids back 2 back then waited 5 years to have next one and having probs with multiple cysts

Yes: Pcos is an umbrella diagnosis that may actually have various causes. The features that lump them all together are: 1) irregular ovulation, and 2) increased male hormones (usually manifested in body hair or acne). There are many other causes of infertility, and cysts on ovaries. Pcos is definitely a possibility for you, but more work-up is required. I wish you well.

Yes: Pcos can develop over time in someone who was normal before.
