how do you know when to get checked out?

I'm feeling grotty today, I really do think it's just a combination of
round ligament pain, having a cold, being sick etc.

But, it had me thinking, most of the ligament twinges are on the low
right side, right where the appendix is, given I'm vomitting anyway, I'd
miss that warning sign of appendicitis. Thankfully despite the fact I'm
sweating and feeling cold all at the same time, my temperature is normal.

I'm also sore in the upper right quadrant, under my ribs, again, it's
not that unusual for me, but with everything else going on, I probably
wouldn't pick up any other symptoms.

Of course all this is 99.9% certain to be just me feeling grotty
worrying about every twinge, but it did have me worried for a while,
particularly because I know that if it really was something I'd be
feeling a lot worse in a few hours and that would give less time for
action and on the off chance anything bad was happening, I'd rather have
time on my side.

I know that I tend to experience a fair amount of twinges early on, it
seems that my uterus needs to get used to having something in it, both
of my last pregnancies this has got to a point where I've been doubled
up in agony and my DH has had to say to me that I really do need to get
checked. I'm starting to wonder if my no scanning unless needed plan
might have actually been better to be get an early scan check everything
is in the right place, then you can relax. If I remember rightly the
really bad pain was a bit later on that I am now, which would have made
an ectopic unlikely because I was past the upper end of the normal
range, but now, at 7+5 I think I'm right in the middle of it.
