Ladies, can someone advise. I've used boots opks this month, I had said I wasn't going to but caved at cd17. Having looked at the picture attached can anyone advise. We DTD (doing the deed) on cd18 & cd19. Probably should have DTD (doing the deed) again on cd20 but was sick. Are these positive? The test line doesn't seem to be as dark as the control line. I usually have a 32 day cycle
