I'd like to join

First time trying SI.
History:
I'm 33. I have cycle that ranges from 26-36 days w/luteal phase of 12-18 days.
I have a history of what I believe to be early chem. pregs. I have had one successful preg. (16y/o son) but had a strange issue of blood/urine tests not being positive until almost 4 mo. preg. and during that time I continued to have a regular (expected time and normal flow) AF. Leads me to believe I have some kind of hormonal issue. We have been TTC for 5 months following 1 yr. of NTNP.
SI:
This month: CD 7 120, CD8 120, CD9 160, CD10 200, CD11 200.
Took SI @ night before bed with the rest of my supplements (baby asprin, B50 complex, multi-vit., vit.C) Started 400mg Guaifenesin CD11 in eve (before DTD). Useing SMEP in addition to Pre-Seed during OV window. I also only allow myself caffine/alchohol for 1 wk. post AF and am limiting pain meds. to Tylenol.
Only side effects since starting SI I have noticed is retaining a LOT water and not sure if it's related but my hair feels different, usually desperately in need of conditioner in shower and now it's not. Weird.
On CD 13 Today and haven't noticed ANY signs of ovulation (my typical is CM and noticable OV pains) so far. Still early for me however.
Started CBE OPK's (smiley's) CD10 (mid-day) & will continue until I get a + or AF.
I plan to take SI CD3-7 next month in similar pattern.
