Hi my cousin is having a bit of a panic, she was prescribed Norethisterone period delay tablets before a holiday and took a pregnancy test before starting them which came back negative. They were taken for about 2 weeks. After returning from holiday she discovered she was pregnant. Although she had an early scan and another at 12 weeks, which showed a strong heart beat and no problems so far. Now she’s worried that the baby might be harmed. Has anyone been in a similar situation or know of anyone who has been and did it affect the baby? It’s difficult when you didn’t know you were pregnant.
