I use the clearblue digs and they are expensive which is the only problem... so I try to save them up because those lines can be confusing and DH understands smiley faces better than lines if you know what I mean!
I bought some softcups on ebay relatively cheap $15 including postage from the UK for 6 of them but I only ordered the other day so I hope they arrive in time for my O day. They don't sell softcups in Australia (haven't passed some medical tests or something) but we are allowed to buy them and have them sent to us. Look for the "instead" brand of softcups.. they have some funny looking ones but "instead" brand disposable ones quite a lot of ladies use and have been successful.
As with all OPKs they say to do digis after midday in case the surge happens in the morning so you can catch it... (I usually do the digi at 5pm after doing a pee line one 2pm and seeing "relatively" positive and confirm with digi if you know what I mean)
I'm doing really well lol... still probably a week till my O day so I just keep charting and testing etc until next thursday then tap DH on the shoulder and let him know its "that time" and show him the smiley face on the digi haha!! I've kind of worked out my cycle so I know what's going on now and just hope that it happens naturally and doesn't take too long... DH really ready for a baby too so lets keep our fingers crossed xoxo
Look forward to seeing your digi pics
Wish you the best of luck for TTC your next little miracle xoxox
