So my boobs had been so sensitive, so i took a clear blue on fridah and it came.back with pregnant, the reason im struggling.is because any test i take.like the cheapos have had like the faintest line like almosy non-existant... wellbi lwent yo thw drs and they did a urine one and it came back negative, so i asked for a hcg blood test and now i gotta wait a week for the results..im struggling hard because i misscarred on mothers day , got thw clear in june to try agian if it was something that we wanted. Now this and.im scare.
