Miscarriage

So my husband and I lost our baby on valentines day this year and ever since my periods have been all over the place ! I’ve only had 2 since the miscarriage one was 9 weeks after and then one 6 weeks after that ! I should of been due on last Friday and still nothing but getting BFN tests 💔😢 I’m booked in for blood test next Wednesday to see what’s happening ! Any one else have a miscarriage and their periods be all over the place ???
