No sex

So now I'm actually getting worried. I am 25 weeks and I can't stand to have my hubby touch me and when I do force my self it actually hurts to have intercourse. 😁😁😁😁 is this normal ? I am normally a very sexual person we live to have sex and now all o da sudden it turns my stomach . I dunno what to do my hubby is good about it but I know it is frustrating for him ! Any advise ?
