Hello doctor my lmp was 22nd february. I suffer from pcod so my cycle is irregular. It is usually 38 days cycle. I had unprotected sex on 8th and 9th march and took ipill twice immediately. It is almost 15 days after the unprotected sex and roughly a week after I have ovulated. Can I go for beta hcg blood test tomorrow? Will it give accurate results? I did one test on 19th it was less than 2. Friday in the afternoon took the last tablet of deviry twice for 5 days, still, I have not got my periods! please help I'm getting very anxious.
