IVF / A lot of sex?

My IVF was canceled a few weeks ago and I've been waiting to get a "peak" day in my opk. It went "high" for a few days but never did peak. Now it's low again. Husband and I only had sex twice in that high window. My period is due in 3 days. Should i just be having a lot of sex in the meanwhile or is it too late? I'm angry at this opk. I was trying to make use of this cycle's eggs since I was already stimulated with drugs, lol. I tested for preganacy this morning but nothing is showing yet. Thoughts on the meaning of all of this and if I should just keep baby dancing? 🤞🏾
