The past few days I've felt a change in my body, my belly seems like it's a bit lower and I have a dull ache in my lower belly and sometimes I can feel some pressure pressing near my vagina....I'm only 32 weeks
The baby is probably putting pressure on your lower body. At this point it doesn't mean anything. If you feel cramping or pain coming and going consistently for an hour call your doctor. Otherwise I'd just mention it at your next appt.
Totally normal. You'll probably start feeling pressure more often as well as new aches and pains. Talk to your doctor, but those sound like normal pregnancy aches.
