Crown: I agree it's not good to travel during the 1st trimester, or even take flight during pregnancy. If i know for sure I pregnant, I wont do it cos have been waiting so long for tis to happen. But sad thing is, if I keep tinking along tis line, I would probably never go travelling until I get pregnant (which is duno when?). Trick is maybe go for free & easy, cos normally accomodation can cancel w/o penalty in advance, whereas tour package harder. ;p
Obese pple harder to get pregnant, that's what generally said, but so far, I also know quite a no of overweight pple who got pregnant, so may not be true. But think it's always good to maintain healthy weight.
Xmassnowy: I also heard a lot of cases where pple "give up" and then got pregnant. Frankly speaking, the time when I got pregnant early tis year, I also sort of give up and was prepared to try SO-IUI the next month then it happened! But maybe for me at least, time is not on my side, so quite difficult to "give up". Also, the other school of thought is to think positive to visualize it'll happen, so if u subscribe to this school of thought, you'll kind of always want it to happen so you don't "give up". I suppose the trick is to balance wanting it a lot and not to over-stress. I find my most stressful period is when my AF going to report, I always feel like I'm taking exam, duno whether pass or fail.
