I got my period something was abit off about it, it finished, then two weeks later i got my period again tyis has never happened before and only went for 3days, normally mine go for 4to5days, then i was ment to get my period 2weeks ago, i did a test that came back negitive. Yesterday i had a tiny bit if blood and some period pain then i woke up today with abit more blood. Could i be pregnant or is my cycle/body being retarded.
