Just a bad cycle??

Sam • I`m 22 and my hubby is 23 we are currently TTC baby #3, I`m so new to all this any advise is more than welcome ❤️
I was due AF on August 10th and I had pink spotting on the 3rd but all my hpts were neg. On Tuesday I started spotting again but it's pink then brown then pink again and only there once or twice a day when I wipe (tmi sorry) has anyone ever experienced anything like this and how did it turn out for you? I'm having my prolactin levels checked next week too.
