I had mirena removed 10th jan and as I didn’t get af while it was in, I’ve been using opk to try and track cycle. I’ve been getting frustrated as they’ve been really low but it went up a little last night so I tested again just now and I’ve finally got a high woo. I’ve never used opks before so how long am I likely to have before ovulation. We DTD last night but should we do it again tonight? Every other day? Does this mean im going to ovulate within the next 24 hours?
