Honestly, I can't tell you how often mine change!
4w - I was shattered and felt a bit sick, boobs barely hurt
5w - shattered and a bit crampy, a little nausea started to kick in. Upset tummy
6w - on the verge on puking one day, fine the next and my boobs changed by the hour from nothing to mildly tingly
6 - nausea 24/7 with a few hours of nothing here and there. My boobs didn't hurt AT ALL about 80% of the time
7 - absolutely nothing to the extent I convinced myself it was a mmc. Went for a scan and there was bean with a decent heartbeat!
8/9 - epic nausea and sore boobs so bad I couldn't even sleep on my front
now (9+4) - no sore boobs at all but dry heaving tonnes and food all smells like pee so all I've eaten are wine gums 🙈
With DS, I felt a million dollars except weeks 8 and 9 when j had a tiny bit of nausea in the evenings. I'm gobsmacked things are so different this time, I'm so up and down.
I guess my point is, symptoms come and go and can be way different for each pregnancy. Try not to worry hon X
