I'm currently taking ovulation tests (cheap ones off amazon). They worked great last month I got a clear positive and ended up being pregnant, unfortunately I had an early miscarriage at 5 weeks so I'm here trying again!

The test states not to use fmu which worked fine last month as I was off work (over Christmas) so I would take the second urine of the day about 11ish which worked out great. Now I'm back in work which means I obviously have to wait until I'm back home and I'm also drinking a lot of water - my urine basically looks as clear as water! Would this affect the test at all? As the lines seem very faint compared to last month - that could be because I'm taking them earlier this month but I don't know??
