This can sometimes indicate a chromosomal condition (Carter 2017, Payne 2016). Your baby has a health problem Your baby may not be producing or passing enough urine, which may be a sign that they have a kidney or urinary system problem. But these medications aren’t usually prescribed in pregnancy (UKTIS 2015, 2018, 2019). These include treatments for high blood pressure (ACE inhibitors or angiotensin II receptor antagonists) and a type of non-steroidal anti-inflammatory called prostaglandin synthase inhibitors (Carter 2017, Payne 2016). Medication you’re takingSome drugs may cause you to have low amniotic fluid. This will help them decide when to recommend that you give birth (Duff 2020b, NICE 2015). Your doctor will keep a close eye on you and your baby’s health. Occasionally, a tear in the amniotic sac can reseal itself, so you no longer leak amniotic fluid (Duff 2020a, Richardson et al 2017). Otherwise, you’ll be monitored until labour starts naturally. Your doctor will aim to keep your baby in the womb for as long as possible, although if there are complications, they may advise you to have your labour started artificially (Bond et al 2017, NICE 2008). Your doctor may also offer you steroids, depending on what week of pregnancy you’re at (NICE 2015). The antibiotic used will be safe for you and your baby. If your waters break before 37 weeks, your doctor will offer you antibiotics to help prolong your pregnancy and guard against infection (NICE 2012, 2014, 2015, Thinkhamrop et al 2015). If your waters break, and you don’t go into labour soon, you’re at a higher risk of infection (NICE 2008, NHS 2017).

If you aren’t sure whether your waters have broken, contact your midwife or doctor straight away. Sometimes it’s difficult to tell the difference between broken waters and an accidental leak of wee, especially if your baby is pressing down on your bladder in late pregnancy. Your waters may break in a big gush, or fluid may leak out slowly, because there’s a tear in the amniotic sac. How long after taking folic acid can I get pregnant?.
