4 days late help

Hey ladies, I am currently 4 days late for af... HPT Negative midday yesterday.
I was due af on 14th and ovulated around 29-31st... Dec14th last af started. Me and my fiance always use a condom ( have done since baby born march 11)... Help!! What's going on!!
We arent TTC getting married in Dec!!!!

I have headaches, really aching back and still having stringy-ish discharge sorry tmi!!
My Periods have been like clockwork since having my daughter...

Advice needed!

Thanks in advance!

Watching this I'm 10 days late. Negative HPT.. Coming of BC however.. I think that's the problem!

I haven't been on birth control since end 2009! We are both very careful no accidents ever   I don't think I'm stressed I'm confident I ovulated as normal... Nothing out of the ordinary accept having antibiotics beginning dec through to the end.. Thus didn't affect dec period either x
When did you test last?

I tested yesterday.. I'm gonna test again first of next week.. If still negative I'm going to see my GYN.. I feel like I should be on my period.. But I'm not.. It's crazy.

I'm wondering this for me as well. I just got my period back last moth for the first time since nov '10. Hubby and I tried for a BFP about 3-4 times. I thought it happened but all my tests are negative and still no af! I have some symptoms but idk what's going on lol!
