I am 30 years old and my so and I aren't trying to prevent a pregnancy but most times we use the pull out method. We had sex on one of my most fertile days last month when he came inside me. he swears he didn't but I wrote down on glow and it was like a 31% chance. well I am not several days late and have taken a couple test that come back negative. I have been very tired the past few weeks and having headaches, heart burn and yesterday a weird symptom... it felt as though I had had rough sex all night. it felt as though I was very raw, it hurt to walk and sit. when I woke today that feeling was completely gone. what should I do
