Ladies have any of you had sharp stabbing pains in your lower abdomen when coughing or sneezing or making any quick movements? So painful it made me curl up in pain for a minute or so then quickly dissipated. Im 7 weeks today with a history of miscarriage. :( im so scared this is only my second pregnancy and my first one didnt get past 9 weeks. :(
