Okay, this may sound like a strange question. We have a trip booked for June. I really want to take one more 'family trip' with my husbands kids before we start working on more kids. But the funny thing is, I am planning on working on more kids around the DW trip. So my question is, how pregnant would I have to be before I would feel it? For example, if our trip is the last week of June would I be alright if I got pregnant the last week of May? I guess not just the sickness, but the tiredness and everything else that goes along with being pregnant. Both of the kids really want a baby but I know that they don't understand the full implications of this. For this reason, it's very important to me to not have our DW trip affected by a pregnancy. At the same time, I am very anxious to start working on a baby and moving the trip is not an option. I'm going to do whatever is in the best interest of the children, I'm just wondering.
