Urine\vagina smell.. Help

I'm currently 9w4d pregnant and ever since I became pregnant me whole down stairs area just smells.. Well bad. I've need checked for all STDs and STIs and I've been checked for UTIs but everything is normal. I drink a butt ton of water.. I don't know what to do. The only time I feel like it doesnt stink is directly after a bath after I've scrubbed with my loofah. I've always been paranoid about hygiene and personal stench and now its beyond my control.. Help. :( any suggestions? I'm a clean person. Its not a fishy smell..
