wait till onset of second trimester.... u will be more energetic by then and also lower the chances of miscarriage...

offcourse u can..

Better to do normal walks, or else yu can wait for 3 months post that after taking advise from doc you can walk..

walking is safe anytine, except if your doctor has advised against it... aapke doctor se zara pooch lo...

Morning walk is always good but as first trimester is considered risky in pregnancy so if possible avoid.
