Incompetent Cervix

I posted before about incompetent cervix. This is my 3rd pregnancy. 2 unsuccessful due to incompetent cervix. I'm on my 28th weeks now and I had a cerclage last December. I travelled here in Cavite last Feb. 1. Yesterday, I notice some stiches fell off. I went to another OB and she requested me several tests like APAS testing just to make sure there are no other reason for my 2 preterm birth. I was kinda hesitant to do the procedure since its a bit pricey and I am currently unemployed. I started steroid shots just in case I have preterm delivery. But hoping and praying that my baby will make till the end. I'm on my bedrest and tocolytic meds. Hope you pray for us too.
