Pregnancy symptoms

I stopped using Nuvaring in November. My first cycle was 21 days. My second cycle was 23. I'm now day 22 of my third cycle. Before using birth control my cycle was 14 days. I have had 'pregnancy symptoms' from cycle 1 - apparently my body isn't used to its normal hormones anymore. Cycle 1 and 2 it was heartburn, cramps itchy breasts and back pain. Cycle 2 my eczema flared up like it hasn't done in years. This cycle the nausea and fatigue has flared up more than ever and I'm so teary, to the point that I couldn't deal with work today. hpt test yesterday (10 dpo) was negative. No bleeding yet. God if I'm not pregnant I really hope this gets better.
