I have been on the Nuvaring for a little over a month now, I had my first period with it Oct. 21 of this year, 3 to 4 days. I inserted a new ring on the right time, on Novemeber 2 of this year I had unprotected intercourse and forgot to put the ring in for half of the next day, I realized and put it in. Ever since then I have had nausea and slight cramping. My period is due in 3 days, November 21. I took a pregnancy test this morning and it was negative. I ovulated Novemeber 2-6. I am assuming conception took place (if it did) Novemeber 4. I have a feeling I am and I do not know what to think. I took the Nuvaring out today but had it in ever since I forgot I left it out.
