On 7th October i had unprotected sex with my partner (we werent actively trying, but we werent trying to prevent either), however on 9th October i had a very light period which lasted 1.5 days, on the 13th October i also had a small amount of brown discharge that lasted maybe 16hours. On 23rd October we had sex, but he wasnt inside me for more than 1min and he wasnt close to arriving (we got disturbed). I did a pregnancy test on 25th October and it was negative. However for the past few days i've been feeling a little off, and feeling a little sickly, not throwing up though just as though ive had too much sweets although i havent. So this morning i did another test just to make sure, but when i did it there was an extremely faint (you couldnt get more faint) second line. Now im kind of worrying/excited/nervous that i might be pregnant. My period isnt due until around about the 6th November. Any advice to say im being paranoid appreciated, and also if i should take another test and when?
