I suffer with OCD really bad since pregnant with 2nd baby,anyone got any hand washing facts that could help me?

I cannot wash my hands less than twice at a time, as i believe that spreading the soap around my hands will spread the germs so i have to then do a second wash to make sure all the first soap has gone and removed all dirt, however if i have touched bins, poo nappy changes, going for a poo myself or handling raw or mouldy food i will have to wash 3-6 times, have been known for more washes in a row but am really trying hard to cut down. Ive been signed up for CBT therapy but cannot start until after my second child is born (im 33 weeks pregnant) Ive never had OCD before, only came on around 10 weeks pregnant. any tips or hand washing facts would be fab- thank you x
