Officially TTC

Ok....so I may just be over thinking things because this is our first month actually being serious about TTC and I've been a smidge paranoid because we haven't prevented before this and I have never even had a close call so sometimes I wonder if we can even concieve..... but I had mild cramps right before ovulation and then didn't have cramps for about two days and now they are back occasionally. By cramps I mean like twinges. I don't think that I have had cramps this early before AF before. AF is not due until around the 24th or 25th. Has anyone else went through this? I may just be over excited about trying. Thank you!
