Hi I am 12 weeks pregnant. Went for scan and everything is ok. I got my 20 week scan date. Shown my manager at work and she said I will have to change my date and time as it will only leave her in work. What do I do was she wrong for saying that. Stupid me went and changed it to when I will be 19 weeks. Can they still do the same checks as if I was 20 weeks. Really I should of gone to hr. But don't know if my manager is in her right to ask me to change due to shortage of staff and she will b in work on her own. Advice needed pls x
