Advise please?

So I started my first round of clomid mid December, I’m on CD 2-6 50mg, I’m very irregular which makes it harder, so I don’t actually really know when I ovulated, I had a scan on CD 19 and the specialist told me she saw follicles and activity.

I’m now on CD37, i don’t know if I’ve got faulty tests or just seeing things, I’ve posted a few tests with very very faint lines bearly visible, better in person. If I was pregnant would I not be getting a stronger line or at least a visible line by now?. I am late but thats nothing new.

I tried a clear blue test but back negative on CD 35, and the one step tests have very very faint lines on them. Had heart burn for the last 5 days now and my nipples are so so sore, do I just give up testing and not bother because I’m out 😕
