important appointment

My first was born at 29 weeks, due to spontaneous labor (believed to be IC but not confirmed) my OB is treating #2 as a high risk pregnancy. we begin Makena injections at our next visit BUT they are also doing a cervical length scan to determine if we will need a stitch. & I am SO NERVOUS! we don't go back til the 29th but I am a bundle of nerves already🙄 Any Advice? Positive stories?👇👇
