Hi im ttc and I have a question. The first day of my last period was december 31 2012 and it went until the first week of january. Ive had sex this month and I had unprotected sex on january 24 and my period still hasn't come yet. Ive had an increase in urination but I think it might be to early. I had a miscarriage in august of 2012. Is it possible that I could get pregnant this late in the month seeing as I had sex on the 24th?
