Thanks for writing to DoctorSpring.com with your health concern.
Condoms have a failure rate of 3 - 18 % depending on the consistency of use.
Also, pull out method is not reliable again because of the pre-ejaculatory fluid ( precum ).
All said and done, a reliable method of birth control is more effective than the Condom + Pull Out method.
Please take a pregnancy test as you are overdue even considering the
35 day cycle length.
All the best
