might not know all the answers but here is a go...
We are not all fertile around 14 days after af, it all depends on how long your cycle is. I ov on 14 day as im on a 28 day cycle, and test positve with a opk on cd13. The only way you are going to know what day is your ov is if you track it through fertility friend or opks. online ovulation calenders do give you a plus minus time frame.
Some tell you positions count, some say not, some say keep your butt up some say dont...i personally believe you call fall pregnant any position, otherwise there would be allot less babies in this world! im sure it helps though having bd and then keeping your butt raised, makes sense spermies do have a easier time reaching the cervix, but hey i believe bd should be fun and seeing we do it so much to try get preggies, why not have a little fun
I do however make dh stay a little longer in me...
and i dont rush off to the bathroom, i wait ten mins or so first, then i know all the strong swimmers should be past the cervix.
My partner smokes marijuana as well, i do read it does effect sperm mobility, ive put him on a vit to try help that. however i have fallen pregnant twice before in the last 7 months with no vit. i lost both my angles though
Hubby has cut down his alot, but i know no amount of preaching will make him stop. I will enjoy a nice glass of red wine every now and then he will enjoy a puff.
How long have you been trying for?
Good luck this month!
