Doctor questions

So my husband and I have just been  stationed in El Paso and just found out that were about 7 weeks pregnant. He just switched our insurance over to prime but it does not become active until August and there's no really close family doctors to me. However there is an obgyn.
I guess what I'm asking is would an obgyn be able to do our first appointment or do they not do that sort of thing? 
Thank you
