I had my last period at the very end of august ending on 3rd september. I am prettey sure i ovulated on about the 15th as i had increased cm (this lasted for quite a few days) so we used protection, we had unprotected sex on about 22nd or 23rd. On 30th sept i had period pains and as i should be due on i didnt think nothing of it. yesterday, on 3rd i had some spotting, i thought it was just the start of my period so i popped a pad on, but i have had nothing since. I did a test last night and it was negative. Is there any chance i could be pregnant and i just tested to early or is it just my period playing tricks on me?
