Is this light light spotting normal?! 4 weeks 6 days! HELP!!

After 4 miscarries this year I can’t help but be super worried that more blood might be to follow. I experienced some cramping yesterday (mild) however had a few sharp pains in lower vagina area and a bit of lower back pain. Is this normal?!! I had 3 blood draws last week and all of them showed rising levels, I am also taking progesterone. Anyone else experience this?
