Some days i had 30, some days 1. And i could feel them from around 14 weeks too so i know what you mean about it being awkward at work.

My midwife told me if they were painful and i had more than 4 in an hour to give her a call but if they weren't painful or they were less frequent than that to totally ignore them, UNLESS they were very painful but infrequent (like really ouchy, not just a bit uncomfy - mine were a little uncomfy late in pregnancy). They're doing work helping to limber your uterus up for labour, so greet them with positivity and don't worry hun.
