Can anyone see a faint line on this? I have long cycles which can be erratic. Average is 40 days but can be anywhere from 28 to 55 days. This last month I used opks for the first time which led me to believe I ovulated around day 26. I'm now on day 43 of cycle. Did test this morning and think I can see a faint line. I've attached a few photos. If it is a BFP will my GP run blood tests to confirm it or just another FMU test? Thanks.
