Uy, totoo yan, first time taking pills is scary talaga, lalo na pag nag-overthink ka sa side effects! Pero honestly, maraming mums sa group ko na nag-start ng pills at nag-adjust lang sila after a few cycles, kaya don't worry too much, most side effects ay temporary lang at hindi severe. Ang best thing talaga is magsalita ka sa OB mo about your concerns bago ka mag-start, so she can explain kung ano talaga ang possible effects at which ones need monitoring, then you'll feel more confident na alam mo exactly what to expect. Three kids na kasi you, kaya deserve mo ng peace of mind with family planning, pills are actually very reliable pag taken properly, and you're doing the right thing by being cautious! You've got this, mama.
