Hello. On Sunday at the pregnancy test after about 2 hours I noticed a barely visible line, on Monday she repeated the test but from another company and also came out the second line very bright, such a shadow of shadow, also visible only against the light. Tuesday/Wednesday I should have been given my period and on Tuesday spotting appeared (bright red, with few small blood clots and that twice I noticed something similar to bright pieces of jump). I was sure that it was a period, but it didn't start too much, the tribe lasted all Wednesday and on Thursday it was already negligible, so I thought it was inplantation spotting, so on Thursday afternoon I did another test, which came out negative (and 4 days earlier there were pale lines). Can I consider the result of Thursday's test to be reliable? Could this spotting have been a miscarriage at an early stage? I will add that I did not feel pain only once when the delicate contractions were barely perceptible.
