Im 35 weeks pregnant with 3rd baby, been told baby is measuring a couple of weeks bigger and is already 2/5's engaged. Iv been sick for past 2 days, had looser stools, feeling pressure down there and unregular tightenings. Anyone else experienced this? Although this is my 3rd baby it has been 18 and 11 years since I did this before and my waters never broke or I never lost my mucas plug with either of them.
