No period:....

Domi

Hi ladies, has anyone experienced this...... I have had no period for 51days (cycle) and I’ve taken 2 pregnancy tests and both have come out negative... I haven’t had any feeling that I’m going to start my period anytime soon. And not sure how to feel about it. I haven’t done anything different with my body and my husband keeps me relaxed so I’m not stressing. Can anyone please help shed a little light with this for us?..
