Hey muncho - chesty cough syrup is supposed to increase your stretchy cervical mucus to help the swimmers hit their target. It has to be the stuff containing Guaifenesin.
I have one son already, he's 13 months and when we were trying to conceive him I had very regular periods and lots of fertile mucus. I did very little to conceive him - no OPK's, syrups, lubes. I conceived him in the second month of trying.
I'm on my 5th cycle now, so I've not been trying forever, but it feels like it compared to last time. I'm doing everything to help the swimmers but my cycles are all over the bloody place and I've got no mucus. I was going to try Conceive Plus too this month but my OH is not so keen. He thinks I'm tampering with nature - if he only knew all the other crap I was taking. lol!
So what are these FSH and sperm tests you're on about? Is this something you do at home?
