So my period is 6 days late now and right now I only have a little bit of brown discharge. I usually always get my period on time. I did have sex but I did not have sex during my ovulating days, I did use a condom but not the whole entire time we used it up until he was almost done. I have been having heartburn these couple of days and I have been dizzy. I have not taken a home pregnancy test because i'm afraid its to early. So could I be pregnant?
Yes, it is possible you could be pregnant, but you provide no actual dates.
"So my period is 6 days late now" If your period was expected 29th April, it assumes ovulation on 15th April, giving a fertile time of 10th to 15th April. If it is a week late, it presumes ovulation being a week late, and your fertile time being a week later.
"I usually always get my period on time" Usually? So sometimes not. Ovulation could have occurred later.
"I did have sex but I did not have sex during my ovulating days" You assume that, but if ovulation was not when expected ...
"I did use a condom but not the whole entire time we used it up until he was almost done" Then what happened?
"I have not taken a home pregnancy test because i'm afraid its to early" What day did you have sex?
So it was unlikely to have occurred in a fertile time if it were a normal cycle. However, if you ovulated a couple of days earlier, then 8th April might have been a fertile day.
If a test taken 8th May proves negative, then one taken in a week's time (13th) should be conclusive (provided you don't have sex again!)
Precum can contain sperm, so that is a risky thing to do.
