Ttc, possible bfp

[Roxieroo]

Hi me and my partner have been ttc for 2 years now. We have managed to catch 3 times but don't seem to be able to carry more than 12 weeks. I recently brought some pro martis one step tests from ebay I figured doing the ovulation tests would Leo me know when's best to try. Problem is I had positive tests 9 days in a row. I know this can't be right as you don't ovulate for this long. So I tried a pregnancy test. This to my surprise came up positive. And was taken with a early evening sample! I then tested for a few days after that with different time samples all coming back positive. Still not trusting the results I bourt a cheep 1£ test and this was bfn. I have no idea what to think. We want this so bad, but doesn't ever seem to happen. Sorry for long posts. Tia xxx
