If you did cheapie tests weeks ago and they were negative and the general consensus was to wait 3 weeks then do 1 final test - would you splash out on a clearblue or will an ebay cheapie do?

had unprotected sex for a few months but am back on contraception now, did tests weeks ago that were neg, but couldve been still to early.
Had heart burn recently and think i should do 1 more,

Should I get a CB? Will that give me a definative answer now that last unprotective sex was over 3 weeks ago?

Have you missed a period?

I think the cheep one's are just as good.

Not missed a period because before I had a natural period after having unprotected sex I went on the pill, and I dont have a break for 6 months as I get migranes when im 'on'.

So its been about 7 weeks since first having unprotected sex and 3 weeks sice the last time, and on the pill for 3 weeks.

I agree that some cheap ones are just as good, if not better than the expensive tests. I wouldn't worry too much unless you missed your period.

Any pregnancy test should give you a definitive answer if the sex was three weeks ago. Can take up to 12 days after ovulation for the egg to implant and a couple more days for the HCG to start showing up on a test. So three weeks should be more than enough time for the hormone to build up so that even the least sensitive test will be accurate.
