Day 38

Hi everyone- I am on day 38 of my second cycle since coming off the pill. My first cycle after the pill was 33 days long. I have been nauseous and cramping since day 28. Also just feeling run down: I am wondering if it's my body getting off the hormones or I could be pregnant. Has anyone gotten a positive so late? All of the ones I took have been negative - we did "try" this month quite a few times but not exactly sure when I ovulated. Thanks for any stories or anything- feeling alone and crazy lol!
