Barbie...If you're already O a trigger isn't really necessary, even with the trigger some dont ovulate until sometimes 2-3 days later. Last time I got a trigger is because it was further in my cycle and if it gets so far they give it to you to speed up the process of your follicles growth, but it isn't necessary, also with it you can't really use opk because it'll automatically be positive due to whats used in the trigger. So I triggered last cycle, still bfn! So it's up to you but it isn't necessary.
I started spotting so I am out this cycle. Onto the next round of clomid.
Also, fertilaid helps with regulating your cycles because mine aren't regular, but it's either that or clomid not both. I did clomid a few cycles, now using fertilaid (which you order online) for probably two-three months and if no success maybe one more round of clomid and if that continues to thin my lining then they'll start me on femara/letrozole. Clomid helps most but it also thins alot of women uterine lining which isn't good.
