pregnant 3 weeks after miscarriage?

Kay
Hi all,
Has anyone else been in this situation before? I miscarried 4 weeks ago and stopped bleeding 3 weeks ago. After having a BFN my doctor told us it was fine to get intimate again. We did not think anything would happen and have been waiting for AF to arrive so we can plan again. The last few days I've had some nausea and constipation so decided to test this morning and got two BFPs. Has anyone else experienced this so soon after mc? Feeling very nervous instead of excited atm 🙁
