Thanks citrus! Sorry it's cd1 for you, but like you say if you've already got your head around that then it's much more easy to deal with.
Jessy- we've not been trying long at all, I took my last pill on 3 March. I think (based on now temping, opks and having only had 1 period off bcp, so not very reliable) that I would have ovulated on 19 April. Checking my tracker we bd 17, 19, 22 & 23 April.
It's possible we did it more than that as I really wasn't focusing on it at all last month, but I don't think we did.
