Quoting Roxanne.♥ttc!!:" I had implantation bleeding with my daughter long before my period was due. I got it like a week after ... [snip!] ... or so if you still haven't gotten a full on period. You know your body best. So just try and be your best judge, good luck!"Yeah I saw a chart today that said I would have implanted on the 19th if I got pregnant on the days that I missed the pills. I just so happened to start spotting on the 19th. This is definitely not a period....I just don't know what it is. I've been on this pill for quite some time and my AF is 3-4 maybe 5 days of pretty moderate flow...not this one panty liner a day thing. Thanks for your input!
