i just finished my first round of clomid...(days 5-9) 50mg and i finally ovulated on day 20.... doc said it was pretty late, but at least i did. I used the opk starting around day 16....
yes you can still use opk's while on clomid. however, there is a higher chance of getting a false positive, especially if you test too early.
i was told after taking it for days 5-9, that i should start testing on day 12, but also bd every other day from days 12-18. you are supposed to ovulated about a week after taking your last pill.
i had low progesterone with my DS and i carried him almost to term (37 weeks) but i had to do suppositories as well as shots twice a week. so i know its possible but its deffinatly no fun
Well even if you did get your BFP this month, couldn't they give you Progesterone right after? I don't know much about Clomid but I'm about to start doing the homework in case I need it. I've heard women who had VERY low progesterone and still getting pregnant and even carrying to term. So just keep praying and if you get a BFP ask for the prosterone right away. I guess you could use OPK's but just buy even more just in case.
Good Luck!
