Urgent answer needed, can I switch birth control tablets mid pack?

[Lovemusic33]

The nurse messed up my prescription, didn't send it through to the chemist, nurse is no on holiday and there's no record of her seeing me ( was done over the phone ), so the chemist won't let me have my pills until I have speaker to my gp. I tried some different pills last month that didn't agree with me ( made me eat more ) so I switched back to my old ones as I had half a packet lying around, I have now finished the half a packet and was expecting to pick some up today from the chemist. So now I am stuck as my go won't see me today, my car is in the garage tomorrow so I have no way of getting to a chemist. I have some of the other pills left, can I take them for the rest of the month? I really don't want to risk getting pregnant.

My partner gets back from working away tonight, making him wear a condom could kind of ruin things ( as we both hate them ).

Are they the same type of pills I.e. Combined or mini pills. Can't see a problem swapping from one to the other as long as there have been no breaks in taking them

What pills are they?
If you can list the names of the pills you've been taking I can help (practice nurse)
