I believe that Levest contains 30micrograms of ethinylestradiol which is the lower dose combined pill.
In that case, as you missed 2 days out of your first week it IS possible that you are pregnant.
These are the 'pill rules' if you want one of the 30microgram pills to remain effective and so you don't want to become pregnant:
^If you miss 1 pill in the first week of your pill pack then use a condom until you have taken the pill correctly for seven days.
If you are in the second or third week of your pill pack then you WILL NOT need to take any precautions providing that you have not missed TWO OR MORE pills. Therefore if you miss one pill in this time you are unlikely to become pregnant.
If you miss two or more pills in the second week you should use a condom until you have taken the pill correctly for seven days.
If you miss two or more pills out of week three then you should take your second pack of pills straight after this pack and should not have a pill-free interval. Again, in this scenario you should use a condom until you have taken the pill correctly for seven days.
The pill rules can be a little complicated which is why most sexual health professionals say you should always take precautions if you miss one pill but this is not necessary.^
Sorry, this is a very long explanation but I wanted to give all of the pill details.
In summary you may be pregnant. I wish you all the luck in the world and hope you are happy whatever the result is.
Let us know how you get on with the pregnancy test.
