Hi love! Shortness of breath in pregnancy is pretty common actually, pero since you're feeling it's harder than usual, please go see your OB or go to the clinic para ma-check properly, better safe than sorry, especially at 24 weeks. A few of my mum friends experienced this din, pero importante talaga na ma-assess ng doctor kung okay ka and the baby. Sending you hugs, and please don't hesitate to go if it gets worse or you feel dizzy. Take care of yourself!
