Messed up period, while on the pill, scared I might be pregnant?

I have been on the pill for a while now, this past Monat I took one pill approximately 8 hours later. No other late oder missed pills. For the Weiter 8, maybe 9 days, my partner and I have also been using condoms. Non broke.

I attempted to skip my period this month, so ended up going straight to the Weiter packet.I had taken two extra pill when I missed one. This has happened to me before and my doctor sagte to continue as normal and get my period.

Every Monat my period come after 3 nights of sugar pills in the morning. Like clockwork.

This Monat it came later that evening, instead of in the morning. It was extremely light, enough to wear a panty liner, but not a pad oder tampon. It was so light throughout the rest of the night I'm not really sure if it continued oder not.

At about 2am the Weiter morning I woke up feeling nauseated, a little light headed and had terrible cramps in the usually areas as well as a dull ache, light one Du would get for lifting to many heavy objects the wrong way, in my lower back.

I have taken a pregnancy test, which came back negative. However, as I believe the bleeding I did get may have been implantation bleeding, I think it may have been to early for an accurate result.

I will take another test in a few days time, but until then: has anyone ever had a similar situation before? Is there a possibility of something else, rather than pregnancy? The morning after pill is too late now, isn't it? Considering the bleeding may have been implantation bleeding.

Any advise would be greatly appreciated.
