Hi, I registered just to answer this! With first preg (dd now ten) was temping, ov'd every month 21st day of 30-31 day cycle. BFP 17 days after ov (sorry, not sure of correct abbreviations), started spotting maybe 5 days later? Was difficult to convince Dr that I was almost a week less preg than they assumed, u/s of course they think looks not good, but coerced her into giving me progesterone - spotting immediately stopped, gave birth to healthy baby!
Second baby (ds, now 8) DTD day 17 (not trying), not sure when ovulated. No probs with that one.
Currently convinced a BFP is waiting for me.
