@rubyroot good luck!
I know what you mean about self-preservation by not daring to be optimistic, I think this is a natural reaction.
In my experience, chemical pregnancies/ pregnancies that ended in early miscarriage, and this pregnancy that has now progressed to the 2nd trimester, all had EXACTLY the same symptoms and sensations in the first weeks. Lots of cramps and twinges, feeling that my period would start any moment. You can see me freaking out about this at the start of this thread!
There’s really no way to tell - it’s so stressful in the early stages! But also, there is hope. Wishing you all the best xx
