Ay oo, normal yan sa simula ng pill, lalo na if first time mo or if switched ka ng brand! A few of us moms nag-try ng lady pills and kami rin napansin yung irregular periods for the first few months, minsan maikli, minsan walang gano-ganong flow, so don't worry too much. Pero kung patuloy pa rin after 3 months or if may spotting in between, or kung may ibang side effects, mas better na i-check mo with your OB para sure lang, kasi bawat katawan different ang reaction sa hormones. Congrats sa taking control ng your family planning, mama!
