possible pregnancy

Hey girls,

So i am worried about possibly being pregnant. not that i have anything against it but at this point i am not ready. my boyfriend and i have had multiple sessions of sex between my last period and now. (last period: sept. 21) every time was protected and we checked before and after the sex. i have been peeing a lot more recently and some spouts of dizziness have came to my attention. should i be worried? could i be pregnant? each time we checked the condom has no holes and was dry. there was a time where i had touched the blanket where he had been and it was wet and that worried me...but i took the condom off of him and he claims that because of how i took it off that it went on the blanket. any commentary would be helpful..but please not negativity!
