Late but negative pregnancy tests

Verushka

So i'm feeling highly frustrated! CD 41, period is 7 days late, no symptoms whatsoever, did 3 pregnancy tests ALL negative and i just came off a nice 2 week break so was not stressed in the least. And did i mention i'm as regular as EVER! The only time i've ever missed my period was when i got pregnant almost 4 years ago! Ttc for 1yr and 5 months and nothing! OB GYN appt. Soon but anyone with the same issues and hopefully had a BFP? #clutching@straws

Update: AF just arrived and you know what i'm actually feeling so relieved! second guessing was driving me crazy! At least i can determine my ovulation etc. Sliver lining i suppose...
