We have been trying for #2 the last couple months and I have had the same thing happen over this weekend. My period was due today, but on Sat. I started spotting a very light pinkish. It lasted an hour or 2, then nothing overnight or all day yesterday until about 8PM, then I spotted again, then again nothing all day today. I did have implantation bleeding with #1, but I don't really remember how soon before my period or how long it lasted, I just remember thinking I had gotten my period. Does anyone know if you have implantation bleeding with one if you are likely to have it all your pregnancies? Good luck to all!
