Preggers?

So I've been sexually active for a while now with my Fiancé unprotected(I know shame on me). We have actually been trying for a baby and This month I haven't had a period. 😳 <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I should've had one on the 17th and that's when I normally have my period. As you can see it's the 26th. I took a pregnancy test in the 20th and it came back not pregnant. I've been having cramps like I'm about to start my period for about 2 days now and my breast have been extremely sensitive for about a week now. I plan to take another test tomorrow. I'm out of town and I already have a pack of test at home no need to buy more. My question is have any of you ladies that are pregnant or have been pregnant experienced this? I'm excited and probably will cry if I get another negative. 😔
