I can't necessarily do it with women I've never met or don't know some what regularly...but if I work with or attend church with someone regularly I can usually tell pretty early. I've never once been wrong when I brought it up and my wife gets completely furious when I ask someone or congratulate someone out of the blue and I'm right.

My boss at my last company was the VP of HR. She came and talked to me once about a co-worker who was weird-ed out by me congratulating her on being pregnant when she hadn't told anyone in the office yet. My boss told me that could get me in trouble some day if I'm wrong.

I asked one co worker one time (after that talk with my boss) and she didn't even know she was pregnant yet but when I asked her she started to noticeably ponder it in her mind and responded with "I don't know, but that would explain a lot". She came back after lunch and told me she took a test and I was right and wondered how I would know when she didn't even know (apparently the project she was working on had her so pre-occupied she didn't even realize she'd been late).

About 2 1/2 years later the same woman came to me, pulled me a side and asked me if I thought she looked pregnant...I looked at her and told her yes and she called her husband and told him they were pregnant solely based on my response. She got a test that night to confirm and I was right.

Then not long before I left the company another co-worker came to me and told me that my boss had told her I could tell her whether she was pregnant or not without her having to get a test - she wasn't. She got a test afterwards anyway as she hoped I was wrong. Funny that after my boss had warned me about doing that she would send someone to me to "diagnose" them.

Just last week my wife asked me if I thought the primary secretary was pregnant and I said I wondered the same thing that day at Church (based on a profile view) but I didn't think she was. She then asked her daughter if her mom was pregnant the next time she saw her and she said "no, why do you ask?"

Funny that my boss and my wife tell me I shouldn't do it but then they both either send people my way or ask me to use this "power".

There have been many others and sometimes their husbands got real upset when I'd ask them because they assumed it was me checking them out too much - honestly I don't even have to "check" them out - it is a glow in the eyes, difference in the body of their hair, etc (all from the neck up) - I don't even have to look at the stomach, etc as I have regularly sensed it very early on when there was no chance of them "showing"...

Oh - with 10 kids my wife used to always want to try to surprise me and she rarely ever got to. Only 1 time was it her telling me and at the time I was in the AF working a job where I was on call every 3 weeks and in those weeks often worked 70+ hours and was going to school full time at night... Other times she'd tell me no when I'd ask, get mad at me, then go and get a test and act mad at me until she was ready to tell me that I was right....

I don't really do it (ask/congratulate) much anymore as lately I just don't care to have the small talk that would go along with it after I ask...I used to enjoy that...now I'd just rather not...
