I'm wondering how soon you can tell if you're pregnant after having sex during your ovulation time frame. Lately and I'm not sure why but my nose has been extremely sensitive to smell, scary sensitive to the point it's freaked out both my sister and my boyfriend on how strong my smelling has become (I could smell my sister and her boyfriend taking a shot of apple pie vodka from the other side of their house, plus being able to smell things from across my apartment) and my boobs have been extremely sore and sensitive along with these weird air like cramps. Then just feeling like I'm too warm. I'm supposed to get my period in a few days but I'm scared to take a test, scared of a negative. But my cervix has stayed very soft and open and is still at a high point as well, along with more frequent small headaches
