I'm 5 weeks and a couple of days, and have been having aches since before I even missed my period. Not really painful, but on and off every day.
Mostly it feels like the ligaments stretching that you get in late pragnancy (although dobtful if could be that, unless the baby is HUUUUUGE), but occasionaly feels more periody.
I have lso been feeling a bit sick - early I know - but have been feeling icky since before I missed my period as well...hopefully a good sign.
I guess I just want some reassurance from others who have had similar but had healthy pragnancies.
