Ubo at sipon

1st day nagka ubo sipon tapos nilagnat ako twice. 2nd and 3rd day ubo at sipon lang. no medications taken. Nag ginger water lang ako. Tapos ngayon 3rd day binigyan ako ng kalabo(oregano) leaves na pina boil. Is it safe po ba? Any home remedies na recommend nyo po? Or medicine na okay for preggy? Thank you.
