Ok I'm on day 37... I let my boyfriend into me for like 2 minutes without a condom... I've read a lot on precum... don't know what to think to be honest... anyway 3 negative tests and still no period... what's going on? Am I freaking myself out?

Of course with a failure rate of 3 to 10 percents condoms are not the best control method. Women get pregnant all the time using condoms.

So how many days late for YOUR period are you, women have different cycle rates.
When do you test, first thing in the morning with the first urine, that is the most effective

Im quite irregular to be honest... one came on day 41... he didn't have a condom on when he was in for the two minutes... im freaking out... the last test I used the first urination of the day and it was negative... that was on Thursday which would have been day 34
