Hi all, so we've been TTC for some time now and because of my irregular cycles we have had a feeling that I haven't been ovulating or at least not frequently. However this morning I have my first ever positive opk and smiley on a Clearblue test (it was negative yesterday). I'm so happy but my husband is in work u til this evening so we can't BD until then!!! I'm so worried that we will miss my fertile window. Any advice would be appreciated.
