Hi TibbyTyler, so sorry to hear about your m/c. I think sex every 2nd day should do the trick. Every day can be a bit hard to maintain & sometimes the sperm isn't replenished as you mentioned. I hope you have success in the 2.5 months before DH goes away. Try not to feel the pressure though - it won't help. Hope to be reading you are pg very soon. PS: It still wouldn't be too late to use OPK's if you want some extra reassurance you are bd'ing at the best possible times! Good luck!!
