leg pain during pregnancy?


has anyone had leg pain, especially in the back of their legs during pregnancy? the back of my legs/my hamstrings have been hurting a lot lately for no reason and i’ve been thinking i could be pregnant. i’ve never heard that it is linked to pregnancy but i’ve had a few other symptoms. also i’m 3 days late on my period, but i did get my first depo shot last month so i could just not be bleeding because of the shot. any input/opinions would be appreciated!
