I'm 19 weeks pregnant and I've still got mine. I use to have 6 boys but when I moved out I wasn't able to take all of them( landlord only agreed to me keeping 2) so my neighbour had 2 and my mum kept the other 2. Unless your midwife says that you persifically cant go near something to do with the g-pigs I wouldn't worry. I'm keeping mine, there never going anywhere lol, if I get to big to be able to get In their hutch and clean them out then my b/f will do it for me. The only thing I can think is that having so many naybe a bit overwhelming whilst pregnant or when baby comes along. but health wise you should be fine. I haven't had any problems x
