Depending on your doctor you probably won't have another one unless something goes wrong.
Depends I only got two my whole pregnancy and I'm 38 weeks. Depends on your doctor and your health. If yout healthy u might only get one more at the end.
If your doctor hasn't mentioned it you probably won't have another. Every doctor is different. Some people only get one. Some get two. Some get several because they're high risk. Also depends on your insurance.
