new here, praying 3rd times a charm

Hello everyone. I have been lurking since I got my bfp on 12/15 but have been super busy and a tad nervous to post. I have been to the doctor one already and had an u/s but was still super early so I'm not really sure of my due date but I am thinking the end of aug.
I have two other children. A little girl and little boy. Our little girl Alexis Lynn was born still on 9/10/09 at 20w6d due to an incompetent cervix. Our little boy Otis Mason was born on 10/8/10 at 21w6d after a failed vaginal cerclage and only lived for a few hours.
I am very excited yet nervous with this pregnancy and even though I am a very active member in the stillbirth/infant loss forums I also like to feel somewhat normal, if there is such a thing haha.
My next appt is the 17th and I will have another dating u/s and also check my cervix. I will also be scheduling my appt with the mfm who will be preforming an abdominal cerclage, through a c-section type incision, in the next 3-5 weeks. I am very excited about the surgery as it is my last resort to ever be able to carry a child to term.
I look forward to getting to know you all. I would also appreciate any p&pts that are sent my way for my lousy cervix.
