It could mean baby has dropped, but not necessarily. Other things to watch for would be your belly looking lower, finding it easier to breath and having less heartburn/indigestion. Some women can feel their babies drop while others never know until the doc tells them.
Hey there, Though it is difficult to tell because I haven't seen your bump before or after these feelings its hard to tell, but, if you are feeling more pressure down there than usual, it is more than likely because your baby is moving into the correct position in preperation for the birth, baby usually engage around 31 weeks for first babies and sometimes much later or not even till birth happens with following pregnancies. For this reaqson I would reckon the pressure you are feeling is most likely your bay getting comfy :) You should keep a close eye out for your mucas plug coming loose (nice, i know) sounds like your baby is raring to come into the world sometime soon! I hope this has helped, also keep an eye out for contractions too :D good luck and I hope your last weeks of pregnancy and the birth are fabulous! all the best from me to you and your baby :)
