Oo, totally normal yan! Sa 33 weeks, maraming changes na nangyayari sa boobs natin, the glands are preparing for milk production, so sometimes they get softer or the tissue changes texture, lalo na kung medyo engorged ka na before. A few of us moms noticed the same thing, iba-iba lang how our boobs react throughout pregnancy, some stay firm, some get softer, some go back and forth depending on the day! Basta check with your OB during your next visit para peace of mind mo, but I wouldn't worry about it.
