We have 2 children now, my son is 6 and my daughter will be 5 months on the 30th. We have talked about having another baby in the future and now there is a possibility that I may be pregnant. I realized we had sex on 2 fertile days ( we weren't paying attention) I have been having very light spotting for a few days now and for the past few days I haven't felt so hot. I may be getting sick because everyone but me in this house has a cold but besides being nauseous and tired I feel great. I am worried about having another baby so close to my daughter because of how hard and costly it will be. I am in college and my husband is retired navy so we do not make a lot of money. I told him that the perfect time would be when our daughter is potty trained but if it happens it happens if it doesn't it doesnt.
