currently having a pregnancy scare. my periods are usually between 25-28 days, the last one I had was 30 days and this time it's day 30 and still not here. is it typical for cycles to get longer as you age or after you start having sex? I've been having my period for four years and the last year and a half it's been regular. I've been under some stress recently but I'm still worried about it's late. I used protection, we had sex on the day after my fertile period and a few days after that, well into the blue part of the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> calendar. he didn't come inside me any time. the only thing I can think of is that he stuck it in for about ten seconds to see if I was fully ready -- then he went back out and put on a condom. that's just precum though, which has little to no sperm anyway. I've taken two sugar pregnancy tests and they're both negative,but I'm not sure if I'm using them correctly or doing the test wrong. has anyone used this method ? was it accurate? I'm freaking out. I know it's silly because all signs point to no and the likelihood is so miniscule, but I need Aunt Flo to show to put my mind at ease.
