Had EWCM this morning. Supposedly 4DPO but now I'm doubting it :( OPK is negative though. Boobs have been sore and I broke out, so I though I might have O'd and it was all progesterone. If only I had temped this cycle! DH and I had sex yesterday, but in the morning -- so I can't imagine this is leftovers from that almost 24 hours later?
