Pregnancy symptoms 7 weeks pregnant

Amy

Hey all! I’m 7 weeks pregnant and my nausea is on and off and breasts are less sore these days although I’m exhausted 24/7 - I saw out little pickle on a ultrasound last sunday and it had a strong heartbeat. I was wondering, can pregnancy symptoms be on and off so much ? I had a miscarriage at 12 weeks a few years ago and I panic about every little thing 🙄 thanks in advance x
