so lost

Ch
So I don't know if anyone can help or have any ideas or suggestions as to what's going on , I suffered an MC in November of last year and since December I've had regular 31 day cycles last being 4th - 8th may and recived a positive OPK on the 19th so I took a test on the 5th June when af didn't show up there was what I would swear was a faint BFP I honestly was in shock and couldn't believe it fast forward to the 6th I wanted to see it getting darker I took a test and was a BFN I've taken 5 tests since then and all BFNs the last being this morning , still no sign of AF either I feel so confused my boobs seem sore , I seem bloated I feel different but I don't know if I'm trying to convince myself something good will come from this :( does anyone have any ideas what could be going on?
