1st round of Clomid and AF hasn't come 3 days late?????

Hi! I just took my first round of  50 mg clomid this past month of days 5-9 . According to the OPK got a positive test back on the 20th of July. My cycles usually run 28 days long. I am never late except by maybe a day. I was due to start on Saturday the 1st of August. It is Monday and I still have not seen AF. I guess what I am wondering is if i O ed on Day 16 of my cycle exactly how late am I or am I even late. I took a HPT this morning and got a negative. Is it still too early to get a +??? Could I be pregnant or just late from the clomid. How long should I wait if no AF comes to test again????? CONFUSED!!!!

Usually they tell you to wait a week after you missed your af and then test again. If it comes up negative then I would definitely see you re.

Nickib85 _ thanks so much. This is so miserable. I have to other kids 9 and 3 years. I got pregnant for them with no drugs at all. This is new to me. I will wait till this Friday and if AF still not here I am gonna give my DR a call. Thanks again.
