My boyfriend and I had sex on the first day right after my last period (5-10 August), and we used condoms as we always do yet at some point he did penetrate me without protection for about 30 seconds. I stopped him and continued only after he slipped on a condom, but didn't ejaculate inside at all. There may have been some precum involved when he was inside me without protection, but I know that compared to other guys I've been with, he doesn't secrete much (very little to nothing) before ejaculation. I am not on the pill, but my doctor prescribed oral contraceptives for me starting next cycle. Now my average cycle length is about 35-38 (it varies) so it is a long one. These days I have been ovulating and nothing seemed out of the ordinary, no strange symptoms whatsoever that would indicate pregnancy like sore breasts or back pain or fatigue or nausea. My vaginal discharge was also regular, but today I noticed some hints of yellow which although don't look unusual made me question the possibility of implantation. I also inserted a finger in my vagina and noticed this milky, creamy, odorless mucous that is absolutely everywhere inside me. This is really what scared me the most because I am not sure if it's normal to have such a great amount of it if you're not pregnant? I never concerned myself with it before and now it just fuels my paranoia. My period is expected in 12 days, so I am not late or anything. However, could I be pregnant or just crazy?
