Hi Ive had the merina now for a little over 2 years after baby number 3, last month i thought it was odd that a had a bleed mid month but didn't think much of it, wasn't heavy but they are normally not. however i did my (not usual) check of the strings and felt the plastic hanging down and as soon as i touched it it came fully out!! now im starting to worry, i did a ovulation calculator and hubby and i (you know!) right on the day!!! ahhhh!!! Im now i a panic, cramping the last 2 days which i would predict would be spot on as im due on on the 12th of this month! any ladies that can offer some advice or experiences would be gratefully received!1
