I had unprotected sex November 15 and the 23. Then November 26 to December 1 I had what was thought to be a period but it super spotty and would come and go. Now my cycles are irregular, but never earlier than 21 days and no later then 29 .. I'm currently on day 35... I took two tests at home both said negative. I waited a couple days and took another one, a first response it had one solid and the other faint. I was thinking probably just a false positive. Still haven't started. All I wanna do is sleep. Could I have mistaken my last period as implantation? I'm only 23 and don't have any kids. So this stuff is still kinda new, knowing what to look for.

Please help
