so confuse

my period usually starts between the 11th or the 16th but nothing so far so I been taking a test and they are all negative. I been giving up hope for the pass three months but this month I notice I'm super late. Took a test today and I still got this...I spoke to my hubby and he thinks I am even tho I been getting negative. So far my nipples are been getting super tingling it's not a day thing it goes on and off but been getting it everyday. Feeling little cramps here and there also almost like I'm getting my period but still nothing...I'm almost hitting a month with no af. I don't want to get my hopes high. Opinions would be helpful
