Ok so i need help. I am TTC boy and I had my first + opk at 1 pm on the 7th the night before it was negative. I am checking twice daily. I had sex later that day and then again the next afternoon i.e the 8th but we could not do it again on the 9th. And now i ma freaking out. Did u time it wrong for TTC boy? My OPK turned negative in 24 hours. I do not check BBT but CM was EWCM on the 8th.
