Last period was 59 days ago, no pregnancy signs and pregnancy test came out negative, what could be the reason?

Some women occasionally skip a cycle for no apparent reason. If the absence of menses continues for more than 60-90 days your doc may offer hormonal pills to bring on a cycle. (if your pregnancy test remains negative.)

It's not unusual to skip period one time. If you have no symptom and pregnancy test is negative, you just wait for the next period. You should only consult a GYN doctor when you miss your period for 3 consecutive months. Good luck.
