My last periods were on 5th november and I have a. Little irregular cycle ranging from 22-27 days but not more than that. Today I did home pregnancy test which was negative but I haven?t had such symptoms like nausea, complete lack of appetite, constipation and weakness. It feels like my taste is gone and I feel like throwing up thinking of most of the food items. Also, my periods were never delayed to this extent. It is a very weird feeling. So obviously I am very confused. Do you suggest that these are just some random changes or should I expect pregnancy.
