Could I be pregnant

I am so confused this month! My cycles run 31 - 35 days. I ovulated then on December 23/24. We had sex from December 21 - 25. Then on December 29 which was just CD 22 I started spotting. I bleed off and on until yesterday. The bleeding was any where from spotting to light flow, and mostly redish in color. Plus I have had nausea off and on for 3 days. Could I possibly be pregnant? When should I start testing?

I'd wait a few more days and test a couple days after you are expecting your period. It is possible that you had some break thru bleeding or it is possible that it is implantation bleeding.

Testing early could give you a false negative if there isn't enough hcg in your system yet. I seems like you could be about 9 days past ovulation, so I'd wait a few more days if you are wanting to test early.

I would not test until the 8th. GL
