Hey, so av got myself in to a little bit of a situation i had sex on the 31st june (around ovulation) then AF was ment to start on the 11th July im usually always 7/8days stright heavy.. This was 3 days just worth of spotting im now thinking was this implantation.. I then had sex on the 23rd July (diff guy) and my period didnt arrive on the 11th aug i take 2 cheapos which come back instantly then went and got a clear blue which come up 2-3weeks... Ive now read that clear blue tests can say 2-3weeks when being even more couple weeks ahead.. Would it be impossible for it to be the first guys baby or is there a chance? Xx
