Symptoms really don't mean anything as "pregnancy symptoms" are the same as those for PMS, stress, illness, hormonal fluctuations, and so on. You can take a home pregnancy test as early as 2 weeks after the time you had sex and that should give you an accurate result. Are you trying to get pregnant?
Just my breasts being sore and feeling really heavy and feeling nauseous i threw up once also
You could still be pregnant whether he pulled out or not because guys have pre-ejaculation sperm. Your cycle is very similar to mine, my last period was on Aug. 22nd and if you had sex on Sept. 3, you would be fertile at that time. Again, the reason I know is because that is my last cycle date and my ovulation calendar has me fertile from Sept. 2-Sept. 6. Not sure what your light spotting could be today, maybe implantation bleeding... You could take a First Response as early as this weekend I think. Do you have any other symptoms?
