Worried

Hi ladies, so I’ve found out I’m pregnant. I’m about 5/6 weeks. I’ve had nausea and tender breasts. Although this morning I’ve woken up with no symptoms at all, my breasts are back to how they were before, not sore at all. I’m getting mild cramps too. I’m really worried I’m going to lose this baby. I don’t have an appointment till February 18th. Has anyone had any experience like this and it was all okay? 🤞🏻😩
