For a while, my MIL would call the DH every week to ask if we were pregnant yet. I finally sat her down and told her to back the F off. The next week we found out we were preggo, lol.
As for lying to people, I am guilty. The hubby and I were concerned for a while that we were having fertility problems so we made an appt with an OB. I talked about it to a few of my close friends because I was scared. Well, 5d before the appt we found out about being pregnant so I called and rescheduled for an 8w. Well, a few days after the original appointment date, my friends called to ask how everything went. I did the only thing I could think of: LIE! And lie I did, lol. I told them that I was waiting on blood work, but that some of the tests were only run 2x a month by the lab (some labs DO only run certain tests on certain days of the month due to costs and time requirements) and that, because of the holidays, timing would get really screwed up. No idea when I would be getting results. I know when I do tell them, they will understand. I feel like a total troll, lol.
EDIT: If people just randomly ask me, I do think I will probably lie and be snarky about it. Even before being preggo, it bothered me that people would ask each other that.
