Hiiii! Yung nausea at breast tenderness ay pretty common talaga sa first few weeks ng Althea, especially pag baguhan ka pa lang sa pills, a few of us moms experienced the same thing din when we started! Usually tumatagal lang ng 2-3 cycles then your body adjusts, pero if it's really bothering you or persistent, best to check with your OB para sure lang at baka kailangan i-adjust ang dosage or try a different brand na mas compatible sa'yo. Ingat, momshie!
