am i or am i not?

hi im 16 from birmingham in the uk

i had thrush and the day after i stopped my treatment for it i had sex with a condom but only recently found out the treatment destroys condoms

i am now 9 days late for my period plus when i had sex it was during my ovulation time

i did do two cheap tests both saying negative but my friend said wait till you are 2 weeks late then go dr's

inbetween my hips where your womb is ment to be is very hard

is there a chance i could be pregnant or am i just imagining it?
