Kellsbells- I had this aslso with my second... Never noticed with my 1st but it became a real issue for me with #2. It felt aweful... Felt like i could feel it between my legs like it was so big and swollen it was gettng in the way...

With My second i was induced and 1 push and bubs was out... I dont even remember pushing... I dont think it would affect the labour... Like you said it is normal but if your concern speak to your OB or GP.

Good luck...Not long now i'm sure everything will go fine... (i too was scared my second one... But all went fine)
