Should I go see a different doctor?

I recently went to the dr and had a vaginal ultrasound done and was told everything looked fine they saw a couple of cysts but nothing to worry about... keep in mind we have been ttc for 2 years now and the dr I went to sent me home and told me to do bbt for 2 months and come back to see him. He also ordered a sperm analysis for my husband, but I feel like they should have done more. Has anyone else had this happen? Should I just go somewhere else? My sister has pcos and endometriosis and she says I should go to her dr because she would do blood work, Pap smear, and whatever else to find out now. Any advice would be greatly appreciated!!! TIA
