questions 4 anyone

my wife and i have done ai on October 25th we have tracked ovalation prior months b4 and we got on track , and when the time came we went to do the ai , so I bled like 2 days and then it stopped sudden ...so I thought that was my period so we waited until it was time to ovalate again in Nov. But guess what no ovulation... we took a few test first couple were negative so we waited a few more weeks to test again then we started seeing a very very faint line ... Is it possible that it's still to early ??? I have all the signs there just a faint ...and I missed my cycle ... so if we are pregnant we would be around 8 weeks has anyone had weird/horror dreams or spine and hips pain???? or knee pain ? I don't have morning sickness yet tho I did throw up in the beginning what other symptoms or things u can tell me this is our 1st ,
