Leaking boobs

We gave been ttc for almost a year now and no luck yet. I fell pregnant many years ago resulting in a miscarriage at 9 weeks. I remmeber then that apart from night time sickness the only other thing I had was my nipple leaking a clear fluid when squeezed. This hasn't happened since (about 10 years) until 3 days ago.

Question is, had anyone else had this and turned out to be pregnant? Due on in a few days so hoping this is it because it only ever happened before in my 1st pregnancy. Just looking for others experiences! Thanks ladies
