keziah I didn't cope well with the first few weeks at all, and neither did my DH. We've gone through two MCs so every day was a nervewracking nightmare.
I did have a 6.5 week scan to rule out a potential ectopic because on eof my MCs might have been ectopic. Usually, all a scan will show at that stage is 'something' growing in the right place - sometimes you're not even sure if its a sac with or without a yolk. I was lucky to see a heartbeat, but have to tell you, the sonographer did not jump up and down with joy because it doesn't mean a HUGE amount. The truth is that most MCs happen between 6 and 8 weeks, so it is completely possible to see a heartbeat at 6 weeks, and then nothing at 8 (a lot of the very critical development happens in this time). Also, I think it is quite unusual to see a HB so early. We knew this, and the result was we ended up paying for ANOTHER scan at 7 weeks just to see if the heart was still beating because I found I couldn't cope with the strain of waiting until 8 weeks.
So I honestly don't know if early scans will reassure you, or make you even more worried. If you see no heartbeat you'll freakout that its not viable and be told to come back in a couple of weeks for another scan anyway; if you do see a heartbeat, it is a guarentee of nothing, which is still worrying. At 8 weeks you should definitely see a heartbeat, and you'll also know you've passed the critical first milestone.
On the pain side of things, you will start to feel weird pains low down in your groin - stitch like pains. Your hormones are starting to relax your ligaments down there etc so they can accommodate your growing uterous. This is normal. But if the pain is severe, or doesn't go away at all, or you feel any pain at all in your shoulder, or if you see a thin 'bean juice' kind of blood, you must contact your EPU and get it checked without delay.
The thing is Keziah, that for the last few years you've been totally in control of your fertility, educated yourself about medical ins and outs, taken vitamins etc and felt like you were at least 'doing something'. What you're doing now is transferring that complusion to 'do something' into this pregnancy because suddenly 'doing nothing' when its become a critical part of your daily life is a difficult habit to break. But the hardest thing about this stage of pregnancy is that it is entirely in the hands of God and nature. You've done EVERYTHING you can to get here - now you need to hand over to nature for a bit. All you can do is wait - and that is incredibly difficult to get your head around. The loss of control is hard hard hard. I know all this because I've walked this walk.
I think the best thing you can do is double check one more time on the drugs and make sure you are taking/not taking what you should be. Then let those worries go. Then you and your DH need to sit down and plan things to do together to keep as distracted as much as you can until the first scan. Eat healthily, gentle exercise, maybe go and see a nutritionist for advice on the right viatmins to take during pregnancy and start those as well. Keep in mind too that as wanted as this pregnanacy is, BEING pregnant is a big thing to get your head around and its not actually the same thing as 'wanting a baby' - your body changing, your emotions, the hopes and fears you'll suddenly have. There's something about a BFP that makes everything more pronounced and in your face. So also use this time to focus on preparing for all that.
I hope I don't sound dismissive or flippant. I genuinely know what you're going through, but you've got to go easy on yourself. Keep talking to us. I have personally found being pregnant incredibly difficult and the last two months have been hell for me and I still have lots of worries about this pregnancy (but that's another post because this is so long now). But what I have learned to develop is patience and stoicism, because I have no choice. And I can't help wondering if this isn't nature's way of preparing us for parenthood, and all the uncertainty that brings. x
