Hi mama! Yes, normal yan sa pregnancy, ang increased blood flow at hormones talaga ay nagiging reason ng swelling doon, a few of us experienced na rin yan around that time kaya don't worry too much! That said, it's always best to mention it sa OB mo sa next check-up para sure lang, especially if may pain, itching, or unusual discharge, better safe than sorry, diba? Hydrate well, wear cotton panties, at take it easy pag may discomfort, you're almost there na!
