I'm 23 and have normal periods

My last period was 6/5/07 and I had it for 4 days. I have a 29 day cycle and had sex on 6/12/07 & 6/19/07

Lmp: 6/5/07 length of menses: 4 days 29 day cycle sex: 6/12/07 & 6/19/07unprotected

Also checked my cervix on the 4th of july and it was very soft and not firm like it usually is now
I currently have light bleeding since yesterday (but not enough 2 barely fill half of the pad)and i used a pad overnight 2 b sure and again same thing ... I dont know if it's a light period or implantation?

I havent had any horrible af cramps like usual...
Just a few mild cramps...I have been really tired and have been having many headaches which is
unusual 4 me, couple days ago I was feeling nauseated, and feel like im getting a cold some days.... Can Anyone help? Has this ever happen and you had a healthy baby?


**any feedback is greatly appreciated and I want to thank you in advance***
