Yea man I would say just go get bloods done if you can.
LGD shouldnt cause that although there have been some cases where it can cause estrogen to rise so it could be but these instances are few and far between. If really nervous again get bloods and sarmsforsale has arimidex as it looks like their aromasin is out or could get from domestic supply to have handy.
I have run LGD many times and have never had that results though.
