First cycle 50mg clomid (clomiphene). follicle of 19x17mm. endometrium 10mm. does this look good? good chance of conceiving? (estradiol 1983 pmol/l)

Looks good so far: These numbers are good so far, and if you are 21 years old (?) and have no other fertility problems your chances may be quite good. I say "so far" though, because you don't say what cycle day this US was on, and what the plan form here is. A follicle 19x17 is good, but generally mature follicles on CC will hit 20-25 mm - I assume you are continuing on? Good wishes.
