Cycle day 63!

Been TTC, last period was 12/29/17- 1/5/18. I have been having lower back pain, frequent urination, fatigue, hungry all the time, boobs are a little sore but not too much. Tired all the time. I feel super bloated. I have cramped a little the last few days. I’ve take 10+ pregnancy tests over the last few weeks and they were all negative! Has this happened to anyone? Also I have irregular periods. But never this long. I have a feeling that I am pregnant but I’m not too sure because of the tests. I just have that feeling!
