My husband and I are married 3 years this year and we decided to start trying for a baby in April, I am 29 and have irregular periods, however I ovulated on 20th April and we made love several times a week before the 20th and including the 20th and 21st April. I have had no period to date but we did take a hmpt yesterday (4th May)and it was negative. How long does it take for your period to come after ovulation and could I still be pregnant?
