Leaving the house

Ok so yesterday I forgot to add some things to the pregnancy so far part of my blog. Didn't miss much so this won't be a long post like the first one was.
So when I was 11 weeks, I lost my plug. Even though I was induced with my son and never saw my plug, I knew what it looked like by the amount of posts I had read on a baby forum about what they look like. A clear jelly like discharge with a blood tinge to it, what scared me more was the blood spots after. I instantly shouted for my hubby, as I wasn't cramping we decided to wait it out.
The next morning I woke up with cramping. As it was the weekend I couldn't phone my doctor, so phoned my out of hours doctors. I was then directed to another number,  who told me to go to my local out of hours clinic. luckily at that point I had only had the 2 spots of blood, it was the cramping that was scaring me.
When I got there of course they asked me about the amount of blood, what the cramping is like etc etc. The doctor that saw said that she'll try and see if she could find a heartbeat, but not to worry if she doesn't as I am still early on, so it maybe hard to find. I layed there scared, knowing that I still had to wait 2 days for my 12 week scan and that it was going to be the longest 2 days of my life.
I heard it, the sound every mum to be loves to hear. My baby's heartbeat.

Ok so now to today's actual post.
You maybe wondering why I've called it leaving the house.
Well, since I was about 16 weeks I've been suffering from dizzy spells that leave me feeling faint, sick and pretty heavy headed. I've only had them 4 times during the pregnancy, but every time I've had one (apart from one) I've been outside, luckily everytime I've been with someone.
Its got me scared of going out on my own, in case the one time it actually leads me to fainting i'm on my own. I've had on where I have been on my own, but I was in the house and sat down.
I have low blood pressure and low iron so I don't think that helps. So all that has left me not wanting to leave the house on my own. Pretty silly really.
