Hi. Not a medical expert pero sharing may experience when I was pregnant. Nagkaubot sipon ako when I was 4 months pregnant din po. The first thing na ipinayo sa akin is boost my Vit C & fluids po pero dahil lumalala ang ubot sipon ko,nagtake ako ng antibiotics to avoid further complications daw. Best to check with your doctor po para may peace of mind din po when taking meds Lalo nat pregnant. Hope that helps.
