I am pregnant and having pains in my right ovary! I have medicaid insurance but its hard for me to find an obgyn... does anyone have any advice?

How far along are you? Have you been seen by anyone yet in your pregnancy?
If it is enough to cause you concern, it is worth finding an OB or midwife. If need be, visit the emergency room. It could be just a normal ache during pregnancy, which there are many, or it could be something that needs to be addressed.
For an OB or midwife, check with friends, co-workers, neighbors, family, etc. to see who they went to. Look into a pregnancy center, planned-parenthood, your local health department. You might want to also check out the Healthy Start program in your state. This would be an excellent resource throughout your pregnancy and after the birth of your baby.
