Hi I was just wondering why my period or I think it was a period has stopped after only one day. My Boyfriend and I are trying to conceive and have been trying for 6 Months and nothing has been happening, Been getting my period on time every month and I got mine on the 1St and it stopped bleeding completely the next day. we took a pregnancy test and it came out negative im just worried whats wrong, if its not pregnancy what other reasons can it be to make your period just stop?
