Kat - I have a Sonoline B, but only because that's what I got on the cheap from Craigslist. I'd just see what people have on there for sale and get one that's used. I can never reliably find 2 heart beats. It's SO hard without two dopplers, bc you can easily pick up the same one in different places, especially as you get further along. A couple of times I've thought I found two, but it's so hard to know. Basically the rule of thumb is if you find two with a HR difference of 10+ bpm you can be pretty sure, but otherwise it could just be variations in the same baby. The only time I KNOW we've heard them both is in the doctor's office when she happened to pick them up in the same field and you could hear them both chugging away. It was weird.
Overall though, any home doppler you use at this point should be about the same - but don't freak out if you can only find one sometimes...until they are big enough to feel moving and find body parts by pressing on your belly it can be next to impossible. My mom had a doppler when she was pg with me and was CONVINCED she had twins bc she could find my HB in 2 different places lol.
Trying - If your CM is not so good I'd highly recommend Preseed. If they don't sell it where you live maybe you can order from somewhere else? Surely they have something similar. Anyway, the Clomid made me have basically NONE and Preseed really helped us a lot. I have no idea if it truly helped with the BFP, but if for nothing else it was nice to have a little lubrication w/o being worried about killing the sperm. If your temp is still high tomorrow your ovulation date might change. I know you don't want it to, but I'm just warning you.

It's entirely possible that CD18 was a fallback rise and your CM trend definitely would make me think ovulation was CD16, but FF may change your date based on temps. I hope it stays the 16th for your sake, but to me it really looks like it could be the 18th.

That does not mean you missed your window tho...keep your head up!! And I could be totally wrong. Who knows?? Only your little ovary knows the truth lol.
Love all the predictions in here! I'll post mine when I get a chance. Hope y'all are doing great - can't wait to see some scan pics today!!
