Brief Answer:
You are less likely to conceive

Detailed Answer:
Hi XXXXXXX
Welcome.
I have gone through your query.

Most antibiotics don't affect contraception. It's now thought that the only types of antibiotic that interact with hormonal contraception and make it less effective are rifampicin-like antibiotics. Doxycycline does not come under this.

From this I can say that you are less likely to conceive.

This provisional advice provided by me is based entirely on the input provided to me. I would suggest examination by the doctor.

I hope this suggestion might be of some help to you.
Take care.
