left back of leg pain

hi everyone, i’m only about 5 weeks pregnant but a few things i noticed has happened. My BPM went from 69 to 80 and the last few days i’ve been having leg soreness on the back of my left thigh (hamstring area) i’m about 10lbs overweight (quarantine and first baby weight) so i’m not in shape and typically i am athletic. Anyway should I be worried?

My last pregnancy (via ivf) this one is natural.. my ob had me on baby aspirin. I don’t typically have high blood pressure but she had a reason for it. I haven’t seen my doctor (well midwife yet) so I’d really like some advice or even experiences that may or may not relate. I will of course reach out to my doctor.
