Aw normal lang yan, mama! 36 weeks pa lang and your body is really stretching out para sa baby, so that tightness and soreness is totally expected, a few of us moms felt the same thing kaya don't worry. I'd suggest checking with your OB about it though, lalo na if it's causing you real pain or if may spotting, kasi they can make sure everything is okay at baka may tips pa sila for comfort positions. In the meantime, go slow with your hubby, use extra lubricant if needed, and stop kung sobrang sakit na talaga, your body will let you know what it can handle! Marami rin sa amin na nag-adjust ng style or frequency lang towards the end, and honestly that's perfectly fine din.
