Hi
I have 2 boys and with both of them I took pre-Natal multis about 6 months before ttc, I temped and obsessively charted and used opk. Close to O time we always dtd every night for about 4 nights and through O..
I didn't exercise. Hubby wears undies in the day but boxers at night. With ds1 he was working in 50 deg temps and ds2 was conceived in an Aussie winter... Hubby still in a stressful job but not outdoors....
I petite and have a mega fast metabolism. I eat anything and everything when and how and struggle to put weigh on.
That's about all I can think of. Good luck in your boy journeys!! My blue dust is all yours!!!!!
