Cycle is all messed up

So apparently my cycle was all kinds of screwy this cycle. AF wound up being 6 days late and lasted barely 2 days. So I go to RE to get ultrasound to check follicles and bloodwork which everything is great so we begin another round of Clomid for days 4-9. F/u 3 days later. I come in the Monday day 11 to get ultrasound and follicles are measuring smallish, meet with RE says we have to look at bloodwork but possibly will ov late that week day 15,16 so start opk. Receive phone call 2 hours later, turns out bloodwork shows I o'd already, est. the weekend before day 12 u/s!! We have been doing iui and this time around was going to trigger but since I o'd off schedule, that didn't happen. This was round 2 of clomid, and would've been 3rd iui for us...so now I'm just hoping we dtd in time for o and that it happened naturally this time around bc we weren't charting nor trying officially, just spontaneously romantic bc we were under the impression we had time. Ugh...did this happen to anyone else and they got a bfp?? AF is due by next Saturday (i believe) but Glow still shows ov for last week and i cant change that. So frustrating...So now I'm reallyyy hoping the witch doesn't show her face...and I actually feel much more relaxed this time around maybe bc I don't want to get our hopes up again?! Lol. Anyways. Thx for reading and t.i.a. for any replies. :)

Edit*: I was also very sick with sinus infection so in addition to Clomid I was taking mucinex...so FX it helped too.
