Yep, but it is all depending on the timing, if it is after ovulation, even by a week sometimes the corpus luteum will give you twinges of pain, but if it is all month long reoccuring I would also guess cyst, I would ask your OBGYN for a U/S. Good luck!
PS. a cyst on your overy can also impead your little eggie from getting where it needs to go!
it sounds like you may have lil cyst ,my friend done the same thing and she found out it was cyst...you may have to go the the Dr...
It could be any number of things. If you are sure it is not ovulation time, it could be a cyst. They are very common and usually resolve themselves. If it doesn't go away soon, you should have the dr check it.
