6 weeks and counting

Ok so we only have 6 weeks before we welcome our new baby girl into this world and my nesting mode is kicking in. HELP I want to clean some of the silliest things and everytime I start cleaning I start having BH contractions. Why is it that we get this OCD cleaning mode towards the end of the pregnancy when that is the worst time because there is no energy what so ever. So if anyone has any suggestions like a cheap house cleaner that will come in and clean my nitty gritty areas let me know :). Have a great weekend.
