I had my lmp on 14/5 and my next period was due on 11/6. I had intercourse througout may (especially from the 23-28 may) and again on 4/6. On 14/6 i did a clearblue test in the late afternoon, which said 2-3 weeks, as well as an ultrasound. The u/s showed a gestational sac and 4w4d. On 16/6 i did a blood test which said my hcg levels are 3095. So did I conceive in may or on 4/6??
