I had unprotected sex on 18/08, a week after my period. I had 22% risk that day as it was my ovulation week. I came off birth control as it was messing up my body. So we use withdrawal method and he always pulls out in time, but this time he didnt say anything and once ive finished he said he didnt know if he came in me or not? How early can i test? Thankyou for any help x
