My partner and I are trying to conceive, and I've had weird feelings in the last week. I've had a mixture of diarrhoea and constipation I know yuk. I've also had craps as if I was getting my period but I'm not close to due. I've also been really tired, and hungry all the time? Should I test ? I'm scared of taking the test because of it being negative every other time and I get so upset. Am I just over reacting?
