Im so confused. If anyone has been through anything similar please help.

So I’ve had 2 chemical miscarriages before. One at 4 weeks and one 5 weeks. What happened with them is I had all the symptoms and faint positives. The lines sadly got fainter and fainter to nothing then I came on. 6 days heavy bleeding and clots.

I have high prolactin levels just diagnosed which I thought might be why, so I started taking vitex last month to try harmonise my hormones. This month, pregnancy symptoms again. I thought I wouldn’t test early I’ll wait until I’m a week late so I don’t get my hopes up if it’s positive, then to lose it again. So tested a week late and it was a very faint positive. Thought it was doomed and tested again and it was a bit darker. Not a squinter a definite line. Then the next morning I had lots of bright red blood, heavy and passed 2 clots then it stopped as quickly as it came. I was expecting 6 days not 1 1/2... so cried my eyes out and went and cried to the doctor who referred me to the fertility clinic. Still waiting for my full period to come. My breasts have been sore and I started to feel pregnancy symptoms again (lost them with the bleeding) . Tested on opk to see what was going on and it was very positive, just done a hpt and:

Weird as it’s darker than it was before I started bleeding, a lot darker....it should have fainted to nothing by now as it wasn’t this dark in the first place
