One way to tell baby has dropped is just by looking at your profile in the mirror. You may be able to just see that your belly is lower. You will also feel pressure and you'll be able to eat a little more and breathe better.
Geez, I'm 40 weeks and the pressure is intense! Theres a trick you can do that helps. It's really hard to explain but I'll try...... it's called the Double Hip Squeeze (u can google it), my doula taught it to my fiance. You turn your hands down, like you are pouring out a can of soda, place your palms on the hips and press down, in, and together.
It feels SO good and it instantly takes away anytime of pressure or pelvic pain. ITS AMAZING!
Cool, he began moving around this morning and has been pushing around all day... so I'm not worried about it any longer.
I'm NOT looking forward to the pressure!
its normal for fetal movements to start decreasing at your stage in pregnanacy.. but if i was you I would do a kick count.. drink some ice water and lay on your left side and see if you can feel the little guy moving. and no 30 weeks isnt to early for the baby to drop however just because he has dropped does not mean labor will happen tomorrow.. my little girl dropped at 31 weeks and I didnt have her until 37 1/2 weeks... you are entering the home stretch :o) and the pressure oh it only gets worse towards the end
