G/C from Due in July! This is a great thread!
We didn't bd that much the month we got our bfp, about four times in total, which was every other day from about CD13 onwards... I actually ov'd earlier that month so it was just lucky that we caught it! I still can't tell you the exact day we conceived as there were no signs, no ewcm or anything and I didn't start testing with ov tests until later so had missed it! Was convinced that month my body was playing tricks on me and was quite annoyed about it!
The one thing I would say to all the ladies who have recently come off the pill or had injections etc is please give your body time to get back to normal and try not to worry if it doesn't happen in the first few months. I came off the pill about three years before we started ttc (I had a coil fitted when I met my husband which came out two months before our bfp) and I reckon it took about six months to get back to normal, my cycles returned to 30/31 days pretty much straight away but I didn't get any of the ov signs until about six/seven months later so it can take a while to get completely out of your system.
Good luck everyone
