Mid 40s - lifted a twin bed to flip rug and felt like a pull in my pelvic area. period is due in 2 days and feel pressure in vagina that i think i have felt before. no pain of any kind but a bit nervous over that pull feeling. i;m physically active?

It is possible you have strained a pelvic muscle or torn some fibers, & that could lead to some sensation of vaginal pressure. Signs of something more serious internally would be nausea, vomiting, worsening pain, fever. If none of those occur, the pain will likely resolve with time, ice & heat, ibuprofen, & rest of those muscles. See Dr if worse
