This was our first cycle using SMEP & Pre-Seed and boom, we got a BFP despite doctors telling us that we wouldn't conceive because I was diagnosed with fibroids at 6 DPO.
I am a now huge fan of both SMEP and Pre-Seed. Together they are a magical combo.
We did not follow SMEP to the T. We DTD every other day starting CD 9 (not 8 as SMEP says). On CD 14 I got my first +OPK and we had DTD the night before so we only DTD CD 13 (-OPK), CD 14 (first +OPK), and CD 15 in a row. So we deviated from perfect SMEP in two ways but we still got the general pattern (every other day followed by three days in a row) right.
FXed for you. I would strongly consider Pre-Seed too if you haven't already!
