Stress out help plz

Hi i been merry for 8 years and haven't been able to get pregnant, in 2010 i got real sick and for the pass year and 8months i been stable. On May first i hat to get my period but no, i started sporting on May 15, 16, 17 and 19 not 18, and that was it. My mom sister and husband wanted me to do a pregnancy test, but because off all the negative one's i have seen in the pass 8years i already lost hope. So on Sunday my husband got me one and i did it, and it confused me because of only have line came out. Then on Monday i did the second one and nothing, i now my husband wants a baby also and i feel really bad that i may never give him. Sometimes i wish he meets someone else and gives him his family.
