I had my period on the 4th of dec. And it ended on the 10th.. my periods are normally pretty regular just as this one was and they come every 20days. I had unprotected sex with my boyfriend on the 8th durin this period.. I also had unprotected sex with him again on the 14th as well. I took a test on the 18th that came out negative. I checked a ovulation calendar and it told me I was ovulating the starting the week after this period. I had unprotected sex again on the 19th. All these times he ejaculated inside of me. I was suppose to come on my period on the 30th but instead it happened on the 28th at about 5am I went to the bathroom and when I wiped I saw some blood.. wth.. THIS HAS NEVER HAPPENED B4.. AND MY PERIOD HAVE ALWAYS BEEN REGULAR.. NEVER LATE OR EARLY LIKE DIS.. AND NEVER DIS LIGHT.. I have taken two hpts the one at the doctor and one yesterday and they were north negative.. is it still too early to detect.. and could I even be pregnant?

Your period may just be late... it can happen even if it never has before. It can be too early for a test to pick up a pregnancy for some women. Give it another week or so; if still no period, try another test. If still negative, see what happens in another few weeks... try another test or see your doctor and ask about having a blood test done if you don't have a normal period.

Since you are trying to become pregnant, make sure you are treating yourself as though you are. Take a prenatal or multivitamin with folic acid, eat healthy, abstain from things you know are not healthy in pregnancy... drinking alcohol, smoking, etc..

How can my period be late if it came too early?.

By the sounds of things it just seems like your cycle was slightly off this month which is normal, you may have never experienced it before but most women will experience an "off month" in time, I would wait until your next cycle id due and see what happens then and if still your cycle has not returned to normal check with your doctor, I hope this helps
