On November 29, I started to get brown discharge, I thought I was getting my period since this usually happens right before I get my period, Wednesday came & its still brown discharge & literally a drop of blood, so I thought this was my period, the next day (thursday) it was gone, that was the end of it

From my calendar I was supposed to get my period on December 1st, the last time I got my period was November 4th, I had protected sex using a condom on November 11th (the condom did not break, we always check after) I also usually get my period a week late (I don't have a regular 28 day cycle, its always a week or two late; though there was one point in high school where I didn't get my period for almost 3 months & I was not pregnant)

It is now December 14th, I am wondering if the brown discharge I got & the drop of blood was my "period" for this month or is this spotting indicating I'm pregnant? But it is impossible if the condom did not break O_O

Interesting... I would definitely do a pregnancy check just in case. Anytime you are having sex there is some chance of getting pregnant. At least you were using a condom though, so you may not be pregnant.

Did you lose a lot of weight that month or exercise extremely a lot? Sometimes that can make a period really light too, especially in someone is already irregular.

First, it's not impossible. A condom isn't 100% effective, even if it doesn't break. If you're having sex then pregnancy is always a possibility.

There are women on this site that were using three different forms of birth control and still got pregnant.

Having said that, it could just be that you're having an off month. It happens to all of us. This is a stressful time of year, stress can throw you off. Heck, I had an off period this month too and I can tell you that I'm definitely not pregnant, my husband had a vasectomy, so it's not a possibility. ;)

Wait until next month. If you don't get a regular period then try an hpt. Make sure you use first morning urine as it's more accurate. Or, if you're really concerned and don't want to wait that long, either see your doctor or try an hpt now.

Good luck.
