Still no proper sickness yet

Hi, so ill be around 7weeks+4days and still no proper symptoms,no proper sickness etc. All iv seemed to have is feeling sick at any time of the day.. not feeling hungry and the thought of having a takeaway turning my stomach.. back ache and stomache twinges etc, increased amout of discharge/mucas white and tinged yellow and feeling tired by the evening. I had a scan at 7wks and all looked fine then so really hoping everything is still fine 🤞. I had a mmc at the start of year so everything is a worry 😫
