Hi
Dr. Purushottam welcomes you to HCM virtual clinic.
I have gone through your query.
I think I have understood your concern, I will try to suggest you the best possible treatment options.
Firstly do n't be scared.
As you have mentioned that you have correctly used condom, so you need not worry.
I hope he has condom on right from the beginning, sometimes there are sperms in the drop of pre cum, and if condom is not on it can cause concern.
Also if you are over date by 4-5 days it is better to get urine
pregnancy test done.
Sometimes- say once in 12 to 14 months- your periods can be delayed , if it restarts in 5 to 10 days and later on becomes regular , please do not worry.
I hope my answer helps you.
Thanks.
