Too early still?

So I had heavy EWCM the 27th-29th so I think I ovulated earlier than Glow predicted but probably not by much.

We only BD once I know😭

Boobs crazy sore which isn't normal unless due for AF.

Got a BFN negative today..is it still too early to test? Or am I fresh outta luck?

(Periods can be somewhat irregular, came on the 14th last cycle.)

Thx ladies
