Dnt worry.it could be just a delayed periods..due to stress also..do a
beta hcg blood test if the value s less than 2 you are definitely not
pregnant..
And yes condoms hv high failure rates , if u people are not planning pregnancy go an a regular pill instead of condoms.
Consult direct once you get the report of blood tests..so that i cn direct you further and also advise a regular pill for nxt cycle..
