Period and pregnancy

Joanna

Hi ladies can you please tell me if you had your period when you were pregnant at all? My doctor says it’s not possible and he thinks my pregnancy is chemical and I may be miscarrying . I am 4 weeks pregnant and 5 days and had blood work done Monday to test the hcg levels and they were very low . My period was due today and I did get it and when I told my doctor he told me to come In to test the hcg levels again today so I went and now I’m just waiting to hear back . I don’t have blood clots but just a period and cramps . Am I going to be ok and is my pregnancy ok and is this just a period or is this a miscarriage ? I’m so devastated
