Hi

For 3 years I have been taking Ortho Tricylen 21. I have had clockwork periods the entire time I have been on these pills. Today I got some bleeding 1 week early to my actual expected period date, I take one more pill tomorrow and then I expected to start my period on Thursday as is usual for me, then I start my next pack on Monday. I took a pregnancy test (First Response) and it came up negative, could be a bit soon too though.

So, could it be that the hormone levels of these pills are no longer right for me, or could I be pregnant and should I stop taking these pills now? Are there any uterine illnesses that I should be aware of in this circumstance and be tested for?

This is highly unusual for me so I am worried...
