Hi StayP. Welcome to the next step

. I advised you to come here, as especially the people who just had a bfn (or many of those still in "limbo") would probably not feel very happy about excited nerves of somebody with a fresh bfp. Difficult not to be excited and nervous, of course, but here many ithers are in the same stage.
It sounds strange, but happy to hear you are exhausted and slightly sick... Symptoms are comforting (although be prepared for them to come and go over the next few days, and for them to get worse in the next few weeks, before decreasing again (causing more panic

)
My clinic did not do bloods, although they now offer them just because so many people were asking about them. It does not really change anything, but might give some reassurance (or not...). I live in a different country from my clinic, but work in a hospital, and have easier access to bloods etc, so fid get myself tested today. Am happy with the result (I am 2 days further than first test in first pregnancy, and hcg is almost exact double of that result, so exactly on course). Reassured for now, but that will not last long...
Cramping is normal, I have episodes of it too (mostly when standing a lot, or when doing some inavoidable physical efforts (having a toddler around means rest is relative, especially as she seems to have the flu: fevers up to 40° since Friday, several bouts of vomiting yesterday morning, coughing and sniffles now...). I am just glad I had a flu jab, and hope it will protect me from (the worst of) what she has. High fever now would probably not be good for the embryo...
Anyway, as long as there is no (fresh/red) blood, cramping is no big issue.
My pregnancy symptoms are not very clear really, and could easily be attributed to other things: some nausea every now and then, some cramps or stabs in lower abdomen, tiredness that sometimes just suddenly overwhelms me (especially after eating), some mild heartburn (especially after eating too much),...
Today at work several people already guessed, as I had to help out somewhere else when my program finished early and some changes were made because I could not do procedures with X-rays. I do not think my boss gave the official reason, but everyone involved knew straight away. So far the "keeping things quiet at least until viability scan", as that is when we discovered things had gone wrong in my second pregnancy.
