4 weeks today! Achey Pelvis

Hello Everyone! This is my 3rd pregnancy, but I miscarried at 6 and 8 weeks the 2 times before:( After 3 years of infertility due to endometriosis and low ovarian reserve... We are pregnant with a miracle baby! We are claiming a full term pregnancy and healthy baby in July! Has anyone else been experiencing an achey pelvis? I'm just a little nervous... Considering my previous outcome. I have no other symptoms other than tiring quickly. Anyone else in the same boat?
