I'm 20 years old and my boyfriend I are trying to get pregnant and it turns out we slept together the day after I ovulated and apparently I was fertile that day. So anyway now I'm five days late and that's really unusual for me to be late it's only happened like once or twice and it was only a day late. But I took a test two days before my period was due and the test came out negative, but I still haven't gotten my period. And also I've been eating a ton more then I usually do and it's weird stuff too pickles and ice cream and Taco Bell and oj lol. And my lower backs been sore and I feel naseous all day my sense of smell is heightened and my breasts are tender. I need help I don't know what to do, am I actually pregnant or is it a false alarm?

You really need to have sex a day or two before ovulation, to allow time for sperm to travel to egg. Takes about two days.

Also how do you know you were ovulating, or you doing basal body temp or other testing. Online or phone estimates are farily worthless.

Next you can not test before period due date for any correct reading,

You need to wait about 14 days after you miss a period to test.

Then use first urine of the morning

You usually won't start having symptoms until your further along... especially cravings and back soreness... I wluld go to the Dr. And have a blood test done.

To me it sounds like you are. Before I found out I was pregnant with my now 11mth baby girl, I had symptoms, I was very very sleepy and tired, and had cravings as well, and lets not say tender breasts:) wait a little longer and take another pregnancy test, and yes use the first morning urine. If it still comes out negative go to your Doctor to get a blood test done. Best of luck.
