Don't want to lie !?? Any opinions. ??

yaya mustan
So I'm Muslim and very religious. I always fast in each Ramadan and this year now that I am pregnant I have been advised by my doctor to not to fast. I will be 6 weeks this Friday and I have not told any of my friends. Only my husband and my sisters know. Now everyone who I call or talk to or meet is asking if I am fasting and I hate to lie. I'm not ready to tell anyone that I am expecting. How should I respond??
