I had cramping but my morning sickness didn't hit til 7/8 weeks. I didn't have implantation bleeding either. I just had cramping waited three weeks for my period to cone and it never came. Took a test. Bam pregnant.
Sounds like a good sign,, I had this when I had ivf , a long few days to wait to test though,, lol good luck
potentially. need to wait til ur period is late doll then do a test
