Symptomps after first trimester!!!

Grace
Hi, im on my 12 weeks now and i know everyone's is different but im a bit confused so i think i will share this.. I will get my first scan next week (in the UK the 1st scan not until 12-14 weeks) so i dont see the baby yet for 3 months having all these symptomps.
Around 10 weeks all symptomps like cramps, nausea, tired, moody, morning sickness is kinda gone for 2 weeks. I mean i still a bit of nausea but thats all.. What weird is for couple days now i feel the morning sickness back and pain in my belly & abdominal comes back a bit sharp or more pain than what it was not to mention my mood swings and all emotional discomfort. Im hoping everythings ok next week on the scan. If anyone have the same story, please share xx
