You had miscarriage
2 months ago and now presents with 2 times period and LBP. Do one home pregnancy
test to check pregnancy status.
After that, you have to undergo one Trans Vaginal Ultrasound
scan and some hormonal
test to rule out underlying pathology for irregularity. It also excludes pregnancy/ conceptional products.
For LBP, you may take some muscle relaxant
tab like ACECLO MR,take hot fomentation or ice-pack, do some exercise,avoid lifting heavy bucket etc. So consult with physiotherapist for better elaboration and guideline for LBP.
You may undergo a Urine test for R/E & M/E to exclude urine pathology.
Take healthy diet, avoid stress and need proper sleep.
Be well and take care.
