6 days late // normally 32 day cycle but on cycle day 38 // PLEASE HELP ME!!

Currently on cd38 w/ no sign of AF. Help!!!!!!!!!!!!!

PLEASE help me. I am confused & frustrated & never been pregnant before.

Long story short:

- Positive opk on cd14 (very positive) .

- Longest cycle (in the past year) 32 days.

- Average cycle 30 days.

- Currently on CD 38 (6 days late).

- No sign of AF.

I've been having:

- Increased CM

- Backache

- Bloating

- Diarrhea on cd 32 then constipation ever since

- Dizziness/light headed

- Extreme fatigue

- Sore boobs & back

- Cramping

- Frequent urination

- Super rumbly tummy that lasts all day

- Heartburn (very new to me.)

- 1 time hiccups. Hard to explain, but they only happen one time out of nowhere and are loud and hurt. (very new to me)

On CD 31 I swore I saw the start of AF. It was dark red tinged CM and I even said, "I'm out this month". But it never happened? Nothing after that.

I'm getting all BFN though. Got blood work yesterday.

So, my question is: Is it normal to get a positive opk and then be late on your period? What is going on?
