Ok this will be long and detailed, I'm 22, never been pregnant before, and I always always have the same expected menstrul cycle. Never been irregular.

About a month ago I started on a new birth contrill pill called Previfem, supossed to be similar or pretty much the same as Ortho Cyclin I believe, anyway, I started taking them after my fiancé and I moved into our own apartment because, obviously I didn't want to become pregnant before our wedding this September.

Well, about a month and a half into the pills, I decided to stop taking them because since I had started on them I was starting to have severe headaches, nausea, severe tenderness in my chest, etc. But keep in note at this time that the first period I had while on the pills was normal, my normal anyhow.

So I quit taking them and was waiting for good time to go back to my clinic so I could request something different, I thought the side effects were too much. I haven't been able to do so as of now.

So now... just this past Saturday, I THOUGHT, I had started my period, you know the normal beginning phase of a period, very very light and spotty for a short time before it really starts up, and for me, by at least 5 hours into my cycle, and most certainly by the 2nd day, sorry to be graphic, but I am like niagra falls heavy.

So you can understand my worries when I am still spotty on my 4th day, I'm talking spotty and light to the point, where it only shows up about 2 or 3 times in a day, and very little at that.
I've taken 2 pregnancy tests, and both say negative, if I were still on the pills I would assume it was the pills causing some kind of a weird side effect, but, I'm not.
And tonight, before I decided to send this out, I felt a very out of the blue, quick sick to my stomach feeling, almost felt like I was going to lose my luch, or dinner or whatever.

So I guess my question is, can you still experience side effects of BC pills nearly a month after not using them, or am I pregnant and most likely getting a wrong reading from the test in a box?
Sorry this is such a long drawn out explanation, but I thought a detailed description would help.

A new pill will cause your body side affeacts as it gets into your system, you stopped taking it your body is wondering what's going on one minnute its receiving this extra hormone then its not.
Its highly unlikely you are pregnant but id see your dr anyway and explain and have them take bloods.
Good luck.
