Sudden loss of pregnancy symptoms

Laura

So I have been so sick since I found out I was pregnant at 4 weeks. On Wednesday I was 9 weeks and still felt so sick, throwing up tired, sore breast, bloated, no energy

Thursday morning I woke up feeling 90% normal. Actually had energy again.

Friday (today) I don’t even feel pregnant anymore

Is this a sign of miscarriage? Would there be any point in going to see a doctor? I’m sooo worried it will end in miscarriage again!
