I'm almost 22 weeks with my first pregnancy and I'm really struggling.
I already suffer with anxiety and people may have seen previous posts from me.
My anxiety manifests itself in OCD thoughts, health anxiety and generalised anxiety.
I've had many worries since the start of this pregnancy, the first one was about the 12 week scan and that there would be nothing there or no heartbeat. The scan was fine. I calmed down for a few weeks, the next worry was the 20 week scan, I worried no heartbeat would be found or a condition would be diagnosed.
I had that last week and all was perfect.
The no worry phase lasted a few days. Now I'm on to the anxiety of feeling him moving regularly and also I've got it into my head I have an incompetent cervix. I'm getting quite obsessed with it and looking it up on Google all the time, which is what I used to do with my health anxiety. I know I'm doing it but I can't stop. It doesn't help that he's sitting really low in my pelvis and therefore I can feel pressure and keep needing to wee because of it. They checked my cervix and birth canal entrance at the ultrasound last Tuesday, no comment was made either way, so I assume that means all was well.
I often feel him really low, it's quite disconcerting, sometimes feels like he's going to kick his way out! 
Another thing causing the anxiety is my mother, I know she doesn't mean to, but because she had an IC after she gave birth to me fine, she lost my would be sister at 23 weeks. She then went on to have my brother and although he was slightly premature, she'd already had a cervical stitch put in.
We grew up with this story and Mum and Dad never really got over it, especially Mum. She never sought any counselling or support afterwards. So as I grew up, she'd talk to me about it, they have a photo and she showed me it. It still haunts me to this day. I know that's horrible, but the poor thing looked like yellow transparent doll. As a teenager, it was pretty terrifying to me. But of course I put it out of my mind as me having babies was a long way off.
Now I'm pregnant and heading towards that date, my Mum is getting anxious, I can tell...she's also said she's not buying anything until 28 weeks because of it. It makes me feel worse, as though she thinks something will happen
I actually had to take a day off work today as I've been so anxious. Every time I wipe myself I'm expecting to see blood. I saw some the other day and it was from a small scratch on my outer vaginal skin which bled considerably because I'm on aspirin.
Anyway, I can't get it out of my head that something bad is going to happen...that I won't be bringing a baby home with me. It just seems too good to be true and something is bound to go wrong.
Sorry for the long and depressing post.
