I feel like my doctors dont care: update

I've been having awful pains for 6 weeks. I've finally had enough of hearing its round ligament pain and called the ER help line. They told me it would be better to call my obgyn and speak with a nurse (even thought I have 3x) so I call anyways and tell the nurse everything and she was so rude! "I don't understand why you're questioning him, you're not a doctor" then she transferred me to the desk to make an apt. She didn't even say bye or anything!

I would believe the doctors but when the pain is making me throw up and only happens when I'm pushing thousand pound tubs and lifting over 50lb parts at work and is only hurting me in one area I it makes me think there is more to it than just normal pregnancy pain. He's fully aware of what my job consists of. I've actually only talked to him once about it. I had to see a different doctor one other time at my 20w scan that told me to Google stretches and the other two times where phone calls to talk to a nurse, all over a 6w period.
