Advice needed, what are you doing?

So I've just started AF again (ugh!) I got pregnant in May and found out it was dead in July, completed the MC aug 2nd, had a rough time, in the ER with a blood transfusion and a concussion. This is my 5th cycle since, and it'll be a year come April.
I'm taking prenatals when I can remember to take them, and up till now I've used OPKS, I've been consistently ovulating cd15 for the last three cycles. So I'm not buying any more OPKS and just going to relax and take my bbt.
Is there anything your taking that has worked for you?
