Possible to be pregnant?

[Moominy12]

I take micronor religiously every day and have a 15 month old daughter.

I had my last cycle on 1st-6th October.

I was poorly a few days after to had to have antibiotics for a week from 11th-16th.

I had sex with my husband on the 19th October.

The last 4 days my boobs have been very tender and my nipples extremely sensitive to the point it makes me feel sick when there touched.

It may just be a coincidence but the last time I had tender boobs like this was over a year ago when I had periods before I fell pregnant.

Could I be pregnant at all? Could the antibiotics have cancelled out my pill 5 days after finishing them?

Think I may just be paranoid

Its a bit early for symptoms, worth taking a test though in a week or so.

It's possible, you're usually advised to take extra precautions during and for up to 7 days after finishing antibiotics. Any change in the levels of hormones in your body (from antibiotics cancelling out the pill) can cause you to ovulate.
