How to keep "down there" from havnt toilet paper trails?

Okay kind of a weird and embarrassing question but here it goes. I've bee. Finding little little pieces of toleit paper( at least I'm thinking its toilet paper) down there. Even if I shower and wash myself really good down there...now that I'm pregnant I have to go pee every two seconds. Im just not sure if its the kind of toilet paper or what..but I'm considering switching to baby wipes instead of toliet paper cause its getting really embarrassing.. Especially when my husband is like......what is all this? When we are trying to be intimate.
