Hun, don't worry about what anyone else thinks. I've been ttc #3 now for 10 months and i dont think you are careless at all. I've also been on the otherside of it where i didnt know i was pg with DD until 12 weeks!

Good idea with the shopping list. Also maybe even buy some off ebay? They are cheap as and they work well according to most ppl who buy them. I found that they work better than the store bought ones. Also buying them online will give you a few more days to get that hcg hormone rising waiting for them to arrive.
