Can you missed a period by 14 days and then on the 14th day start and have it for 6 days and be pg

Not likely.

Normally no, normally it is just a late period, if common for many women to be late once and a while, keep a eye on next month to be sure.

Most likely an off month. It happens to all of us at least once in our lives.

Fact is, you got your period, so pregnancy isn't likely. Doesn't mean it's impossible, just not likely.

Another fact. We can't tell you what's going on, not online. You'll have to wait and see.

Good luck.
