Am i freaking for nothing..

Took plan b last monday (8th oct) after having sex and our condom failed. It was only a few hours after my period had ended and i took the pill 8 hours later. Again we had sex monday 15th and the condom broke AGAIN. I took plan b again about 10hours later. I know this will mess my cycle up pretty bad (expecting my period in about 2 weeks) Ive had a uti since the first time the condom broke because i forgot to pee afterwards and have had a lot of cramping and back pain along with it (ive finished my course of antibiotics and have another appointment on friday to start on a more reliable form of contraception as condoms seem to be failing us and get more meds if i need too) Ive also been feeling a bit sick and im really stressing out which i know can make my period even later than what it will be, if it even comes at all.
