###Human: Do ovarian cysts cause pain during pregnancy? ###Assistant: Hi. Both the cysts one of 2 cm and other of 3 cm, and one luteal cyst and one hemorrhagic cyst respectively are insignificant and has no concern with cancer at this size. On and off pain during pregnancy do happen but this cannot be ignored if it is very severe. You had your USG done at 5 weeks and now you are 8 weeks 5 days, but pain is still present on and off. You have not mentioned about the cardiac activity of fetus in your last scan.  So, it is better to repeat your scan to know about the cardiac activity as well as the size of both the cysts.  Regarding the ovarian cyst we have to see whether the size is increasing, decreasing, or it is the same. If it's increasing then it is of concern (if more than 5 cm). If it remains the same or decreases, then nothing has to be done, as it will regress on its own. So, repeat your scan now instead of repeating it at 12 weeks. As you have told me about the family history of breast cancer, I advice you that in future you will have to be vigilant regarding the same. Revert back with the scan reports to an obstetrician and gynaecologist online.---->
