@theblueflowers - this is my third pregnancy following two miscarriages, technically both missed miscarriages picked up on early scans.
I got 2-3 at a certain date, expected 3+ one week later and it didn't happen, got 3 + 2 days after expected...
Now, I'm a bit of a fraud being here, as I'm already 8+4, my last scan was 7+5/6 with a strong heartbeat, so fingers crossed as this is the furthest I've come in terms of growth. I've become a bit obsessive having many private scans though, hopefully I can back off from those soon...
I wanted to mention sickness as I can see the is is a big theme / topic of convo here. I've not thrown up once. I have heavy and sore boobs, which are big anyway so it can be a nightmare! I also have nausea of varying degrees at varying times, often enough to make me sick a little in my mouth but never full on sick.
I've also noticed that pre pregnancy 3 I was eating a lot of rubbish (try not to judge haha) to console myself following the miscarriages, it started at the point of loss. I would eat crisps chocolate and ice cream after dinner. Now the thought makes me feel ill, so I can eat something sweet after dinner, I.e. and ice lolly and maybe a few bits of chocolate but I can't stomach a lot...
I do feel bloated and I'm up every night from before the alarm to pee.
All these are positive symptoms I know, but I'm continuing and functioning in day to day life. A) I guess that makes me very lucky B) it panics me that because I'm not super sick I'm going to lose the baby. That wasn't my point of posting though! It was more to give reassurance that at least up to 7 weeks + 5/6 my pregnancy has been going perfectly. So for those who aren't too sick, it's not necessarily a bad thing...
A friend of mine had her son 18 months ago, she didn't even find out she was pregnant until 8 weeks (I'd have loved that luxury with no obsessive testing haha!) - point being, her symptoms were obviously very mild until that point for her not to clock!
I have another scan tomorrow, so wish me luck
honestly, this experience is so scary, the nerves are just something else. Every week feels like a year, but here we are and I've made it through these nerves for nearly 9 weeks now and so can you!
In my obsessive reading, I've found that after 6 weeks with a heart beat, the chances of everything being ok are 78%, after 8 weeks, the chances go up to 98% so for me, I think I can gain a lot of comfort when I have a scan past 8 weeks 
I hope you all have wonderful and successful pregnancies.
Is there a FB group I can join? If I can get through the 9 months it would be great to join a group of people who are in the same situation
