I had my last period on the 18th May 08 and had sex with my boyfriend the day after my period had finished which was the 19th and 20th which he used a condom but loads of pre-cum came in contact with the condom, as i touched his penis, a bit of pre-cum went on my hand as I was trying to put the condom on, would this get me pregnant? also it's 4 weeks and 1 day ago i had sex with him and on the 13th of June I started to have cramps in my belly and a day or 2 later I started to bleed lightly almost pinkish then it went dark red with tiny bits of blobs of clots and i bled for 2 and a half days with darkish red then it started getting light and lighter and stopped but on and off, and now it's going light brown, my period is usally quite heavy and lasts for 4-6 days, is this implantation bleeding or just a light short period? I am so confused as this is my first time in experiening this, someone please let me know what you think xxx %-)
