Mama, I'd really encourage you to try calling your OB clinic again or visit as soon as you can, cough and sipon during pregnancy need proper guidance from your doctor directly, kasi iba-iba ang safe options depending sa stage mo ng pregnancy. I know it's frustrating waiting to get in, pero honestly mas better safe than sorry, a few of us mums learned that the hard way! In the meantime, try to rest as much as you can, stay hydrated, at kung you're having trouble breathing or feel really unwell, don't hesitate to go to the ER na. Rooting for you!
