Implantation or early miscarriage?

I'm 4 weeks and 7 days pregnant. I had my implantation bleeding on the 8th and the 9th of dec 08 it was spotting of pink blood. today is the 10th and now i'm having a light bleeding that is light red. my period doesnt come on until the 16th. I never had bleeding early before my period. My signs are just my lower back hurting 3 days before period. I dont get cramps but with this "implantation bleeding" i have on and off cramps. What could this be. I had sex on my fertile days 1, 2, 3 of dec.

Ok first off how can u be 4wks and 7days pregnant (which is actually 5wks) if you arent even due for your period yet? You are usually around 4wks when your period is due to start not a wk before....???
Secondly your inplantation (implantation) bleeding usually occurs in wk 3.

With those dates you wouldn't even know that you're pregnant yet. Have you gotten a positive pregnancy test? If so, then your dates are probably off. Also, if you are pregnant and have any bleeding you need to call your doctor's office and let them know. They may want you to come in and get your blood drawn.

If your period isn't due until the 16th of December then you are only 3 weeks pregnant. Technicaly just over a week since conception. Did you take a pregnancy test?

I agree with these ladies but if your really concerned I might suggest going to th E.R. right away. Wish u the best of luck

This is very confusing...implantation bleeding happens shortly after ovulation NOT while you are five weeks pregnant...see a doctor so you can figure out what is going on...
