I notice with the ones with thicker lines, ie, not frer, its easier to see the "shadow" effect of the second line which can look like a bfp. Been there done that and its depressing!

The cheapest i've found frer is $12 for 3 but postage $6.50 which would mean i'd have to buy in bulk to make it cheaper than in store. Its still over $3 a test, can't really justify it because I know when I have them in the house i use them, daily, sometimes more than one because i either think i see a line and need to re-check it, or i convince myself the bfn test must be a dud and i waste another one to double check! I'd also make a point of not buying to force myself not to test, to wait, but then i'd cave in and make an excuse to go to the shops to buy more. I don't know if its because i was told i was miscarrying, then that i wasn't but that the hcg wasn't going up normally so i relied on testing every day just to see the line getting darker. Now I'm really scared i'll have another m/c, and although i told myself just to leave things this time and wait, its so hard!
