Help please we have been using condoms and I was due my coil fitted this week as my period was due last Thursday so I’m now 5 days late. But last month I was 10 days late so I haven’t thought much of it, my baby is almost 4 months old so my periods have been very different from before I had him so last month I had taken a pregnancy test which said I was not pregnant which I never thought I was I didn’t feel pregnant I was just ruling it out since I was 10 days late. So this month I had ovulation pain and counted 14 days from that and I’m now 5 days late and thought I can’t be pregnant because we are careful but I bought two cheap tests from Morrison’s and took them both just before. Could they be wrong? I never used cheap tests before
