I completely understand your anxiety. You sound identical to me 2 ectopics (medically managed) and several mcs. Had given up and along came a surprise baby at just a tad younger than yourself.
That line progression looks great! Almost a dye stealer.
I used the clear weeks indicator the last time and tested with one of those every week for 3 weeks. But, I did that from as soon as I tested positive. I was even doing tests up until I had a private scan at 6 wks.
Your blood sounds great as well.
You can, due to your history self refer to your local EPU. They should offer you a scan at around 6 wks.
I couldn't get in before 8 wks 5 days, so went private.
I even had what I was positive was the same pain I had with the extopics which was a dull constant pain in my right hip. Both ectopics were right sided.
Turns out I even ovukayed from the right with this baby.
I'm not going to tell you to relax. I won't patronise you. Because I didn't throughout the whole pregnancy. Once I knew baby was in the right place, then I was worried about mc. Then late mc and other issues. It's hard to give yourself hope and excitement.
I ended up being so unprepared for baby when I delivered early, we had to order all the baby gear while at hospital posy delivery.
Good luck and tentative congratulations. You're in for a bumpy ride no matter how this goes.
