I have a question ladies !

Okay, so I had a regular 27 day cycle before I had a chemical pregnancy in November . Now it's all effed up anywhere from 27 days to like 30- something . Never really past 32 . Well , let me cut to the chase im cycle day 34 and I've been having cramps the last few and lots of thick cm ,  nothing major just some mild cramping . I've taken 4 pregnancy tests and they're all negative . Do you think I'm late and I just don't have enough hormones to show up on a test  ? Or do you think my period is still just messed up . It's been 7 months sheesh . You'd think it would be back to normal by now . 😩 opinions ?
