Baby Dust PLEASE

My fiance and I tried ovulation strips for the first time since ttc and yesterday morning got a clear surge. We're also trying out preseed for the first time as well. We've had intercourse multiple times since then but not too much. (Not trying to drain him) please send baby dust our way. He's in the Marines and leaves for 2 months next week... I'm so scared cause it'll be the first time he's left me since we've met.. baby dust and prayers please
