I know it has been ages since I posted. I've felt oddly caught between my good fortune and my on-going worries and just haven't figured out how to post what I want to say without sounding like I'm whining or spoiled or something unpleasant.
Today I'm drawn back here because I need the support of this community and hope that writing it down can help ease my fears. Okay, my irrational fears.

I'm 16 weeks pregnant, isn't that wonderful? I even had a few weeks where my worrying got much better- from the first week of November until Thanksgiving, I was doing pretty well! On Thanksgiving afternoon I had a bit of blood tinged mucus and have been thrown back into the anxiety pit ever since. I called my doctor that day and she thought it was probably due to over-exertion (I'd been standing and rolling out pie crusts and hosting 14 people for the holiday). It didn't get worse or return and I've been fine ever since. Yesterday I had a prenatal visit and a quick ultrasound and all was well. I've been able to hear the heart beat with my doppler and it's a wonderful, if totally unreal, feeling! However, since Thursday, I've been completely, irrationally terrified that I might have cervical insufficiency or otherwise go into extremely pre-term labor and lose the baby and I don't know how to stop worrying!

My doctor at the visit yesterday said that they'd check my cervical length at my ultrasound at 19 weeks (only 20 days from now!) and that there was no reason to suspect that I had any problem. I know she knows what she's doing, but I'm still not convinced. I'm pretty sure I'm just being irrational and nervous due to my history and extensive knowledge of what can go wrong. Nonetheless, I'm really struggling with how to get this fear under control, so I thought putting it out there might help.

Still worried

I don't know if I just have an overactive imagination or if I'm experiencing doctor appointment/reassurance withdrawal, but I'm having one of those nervous days today.
We had a great appointment on Friday and things definitely looked good. Today though, I am worried. My breasts aren't so sore today. They were sore and achy overnight, but once getting up this morning I haven't noticed much (and believe me, I've been checking). I thought my symptoms would be increasing here in week 6, but aside from a little breakout, not so much. Am I anxious because I have reason to be or because I'm getting ready to go on a trip and I'm generally concerned about my luck with regard to pregnancy?
Either way, today isn't feeling fun.
