can ovarian cyst cause contractions?

Hi,
Welcome to ehealthforum,
The abdominal/uterine contractions in later pregnancy usually signals possibility of premature labor/uterine activity. Do not ignore your symptoms. Visit your gynecologist/obstetrician for further evaluation and assistance. It is important to rule out premature labor pain and fetal distress. Appropriate measures would be taken to ensure lung maturity and safe delivery of your baby if it is due to premature labor. If the baby is fine and these can be controlled, you will be put on uterine relaxants to help with carrying on pregnancy till term.
If premature labor gets ruled out, further evaluation would be needed to look for other causes. Treatment as appropriate based on the examination findings and investigation results would be started to help you in controlling your symptoms. Be in regular monitoring and follow-up with your treating gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
