I believe that the worse thing that can happen to one lady is late period and negative pregnancy test issue. I went through this so many times and whenever my pregnancy test is negative I keep asking myself - what is going on with me?
You need to ask yourself a couple of questions and you need to be aware of some facts in your life - for example, are there some huge changes in your life?
Are you on diet, maybe you have lost a lot of pounds or you gained some?
Are you stressed?
What are the reasons for this stress?
Those all are possible reasons for your late period.
I am experiencing similar symptoms.I am usually regular with a 25 day cycle and i thought i was pregnant because i am 6 days late and no period.I have no tender breasts, but more fuller and i feel i cant fit into my clothes lately from 4 weeks ago.I tested negative to pregnancy test and still baffled.Ive never missed a period and was only when ive been pregnant in the past with my 2 children.I feel like my hormones are playing chaos on my body as i get palpitations more so at night in bed and cant sleep properly and skipped/double heartbeats i sense strongly..that can last 2 full days and then come back 1 week later (now).I take thyroxine for hypothyroidism and was told to half my dosage this month.I believe this has caused me to skip period as i must be low now and feel tired more often.I wonder if having a cyst will stop cycle..but i cant see why as it must be related to my thyroid.I am seeing my Dr this weekend to confirm blood test for both pregnancy and tsh thyroid and then determine what is going on.I have never had this problem 2 months ago or ever and believe something is wrong somewhere.Fingers crossed its not heart related.
