I did my first round of Clomid about 2 weeks ago. My period is 4 days late, but HPT says negative.Insight?

Answer 1

When using Clomid, your previous cycles are irrelevant.
After you take Clomid you can expect to ovulate sometime between 5-14 days after your last tablet. And then after ovulation you can expect your period to start about 14 days later.
So, after your last tablet of Clomid it could potentially take 4 weeks for your period to come--2 weeks after last tab to ovulate+2 weeks to get period.
Since you only took the Clomid 2 weeks ago and you are not late yet.
