I've actually just had this happen funny enough. I'm 37 weeks. On Tues night i was laying on the couch and it felt like i wee'd myself, however, i had no control over it and it didn't smell like wee. I rang my Mum for advice who told me to ring hospital. I was told it was probably just my hind waters but to pop a pad on, lay down for 30 mins, stand up and phone them back. I did that. Told them i had clear goop on my pad. Was told it sounds like mucus and not to worry. I kept losing more mucus on Wednesday and Thursday. By Thursday it was looking a tad orangey so i rang the hospital again just for advice and reassurance. I ended up popping in. I had bub's heart rate monitored and they did an internal swab to check if it was amniotic fluid i lost which it wasn't so i was sent home. I was told an increase in mucus is common around this time. Sometimes when i stand up it feels like the tiniest bit of wee is coming out of me but i am told this is all normal. My main reason for going to the hospital was to make sure the waters that broke weren't the real deal waters (which i didn't think they were coz i had my labour induced last year with my son as he was still born and i recall those waters being a massive gush). The midwife encouraged me to go back for a check up at the hospital if anything else changed or i became concerned again. I was really appreciative of the whole "we don't mind" attitude.
