Ay, normal lang yan usually after CS kasi ang uterus pa rin gumagaling, a few of us had the same experience, spotting here and there for a few months pa talaga! But since you're 2 months post-op and this is happening after your period stopped, best to check in with your OB just to make sure, lalo na kung malakas ang bleeding or may cramping na painful, para mapigilan ang worries mo. Healing after surgery is unpredictable talaga, kaya doctor can reassure you better!
