Am I pregnant ??

Hi everybody !! My husband and I have been married for 2 years. He is 28 and I am 22. We just started to try to concieve last month. Fingers crossed!! I am 3 days late on my periods, but I took a pregnancy test 2 days ago which came out negative. My breast are really sore and i get cramps frequently from couple of days. I don’t know if I am pregnant yet. This seems so confusing and I am so nervous.
