Can I be pregnant after my tubal 8 years ago?

Ok here it goes if too much info sorry! I had a tubal with hulka clips 8 years ago. I have had very normal periods since then. I got married to my dream husband last year. So in March I was late on my period 8 days. Then April came and it was normal. Then May came and it was normal but lighter than usual. So now we are at the end of June and no period. My ovulation calendar said I would start ovulating 6/29. Now all this time that I have been late I have been showing signs of pregnancy. I always feel wet down there and my boobs are heavier and when I touch my nipples they feel wet too but nothing on my bra. Is it possible that I could be pregnant after all these years???????
