Endometriosis, Just Pregnancy Or Something Else?

All the women on my dads side have had endometriosis, About 2 yrs ago I started thinking I have it as well. I have mentioned it to my doctors but none of them have really taken me seriously. So now I am about 4 weeks & 3 days pregnant, I have my 1st appointment July 2nd, I have been having on and off cramps. They are almost like period cramps but a little worse due to me thinking I have endometriosis. So my question is has anyone been diagnosed with endometriosis and if so did you get pregnant and have cramps as the usual or a little worse? I will be bring it up to my doctor when I see her, maybe she can shed some light on this. Also I am wondering as well if it's the braxton hicks, since your body does go through it once your pregnant, some just don't feel it, or so I have read. Or maybe is this just the pregnancy itself? I am very confused about this, since I didnt have this with any of my other pregnancies other than my miscarriage and blighted ovum pregnancy. Anyways Thank You for your time and have a blessed day/night.
