Hello, so my last period was dated March 22-26,2021 and up till now I haven't gotten my period yet. I had this period tracker installed on my phone and it says that I should've had my next period by May 1-6 which I already missed those dates obviously . I've always had longer cycles. I had 39 days, 42 days, 45 days, 55 days and for the record this is the longest one which is 86 days already. 

I'm actually planning to schedule a check up to know what is wrong with my cycle. It drives me crazy because I did have 5 pregnancy tests already and they all came back negative. I just wanna know if what the hell was wrong and why did I have this longest cycle. 

I also think that maybe this is just because of stress because last April I've been through series of stressful situations. I've been emotionally unstable that month for some reasons I couldn't disclose.

I'm also checking myself if I'm showing any preggy symptoms. I did have light to moderate cramps (same as menstrual cramps), also noticed slight increased in my cm (cervical mucus) but apart from that I don't feel anything like nausea or morning sickness. Though sometimes I did feel extra tired whenever i get home from a long day at work (idk if does this event count tho) I also don't have any food or smell aversions.

I would like to read some advice if what are the next steps should I do. This missed period has me really stressed out. Hope that anybody here could help me,

Thanks.
