33 wks Rapid erratic heart rate

I’ve been trying to reach my doctor since yesterday but somehow have yet to get ahold of anyone😩 my heart rate over the last few days has been really weird like resting I’m anywhere from 120-136 and literally standing up or sluggishly walking has it jumping as high as 175 I feel like this is super not normal but I’m not sure what to do as no one will freaking respond I was initially trying to reach my doc because I’m having signs of a clot in my right leg but again haven’t been able to reach her my husband literally just went out of town this morning and I have two kids ages 5 and 7 I don’t want to drag them to the hospital unless my doc tells me I should go but I feel like the heart rate I’m having I should probably go idk because they freaking underplay everything I complain about like oh it’s just pregnancy but idk what to do 😅💃🏻💃🏻
