Bleeding at 4 weeks pregnant. 2nd Miscarraige?

Hi, I wonder if anyone has experienced this, I feel absolutely desparate.

I had a missed miscarriage at 11 weeks about 2.5 months ago. Me and my partner were devastated, I had no idea it would hurt that much. We really wanted the baby and were so excited. I felt safe that I had got nearly to 12 weeks but I started to bleed, just a bit, and we went for a scan and the baby had stopped developing and died. So I had to have surgery to remove the products of the pregnancy which was hideous.

We decided to try again straight away. We are so ready for a child, our life is starting to feel empty without one. I waited 5 weeks for a period after the surgery and once I knew my cycle was back to normal we had unprotected sex all month. Last Friday I took a pg test as I felt weird and it was a faint positive, then again on Sunday I took another one and it said 'pregnant 1-2 weeks.' So I definitely know I conceived. We obviously didn't start getting exited as we have been there before. I felt scared but optimistic, surely I can't be that unlucky, I have had a ton of other stuff happen to me this last year and I felt like this is my chance.

I woke up this morning and went to the loo and there was blood when I wiped. Just a tiny bit. I have wiped a few more times since then and it has pretty much stopped now . A very small amount and looks like old blood rather than fresh red blood. I don't have any cramps, just the odd twinge in my lower back but I was having that anyway and had that in my other pregnancy.

Has this happened to anyone? How did it turn out? I rang the early pregnancy unit and they said 'nothing we can do' They can't see anything on scan until 6 weeks to I just have to wait. If no more bleeding then it may be the baby is okay. I can have a scan at 6/7 weeks or do another preg test at 6/7 weeks.

I am losing my mind. I came into work because there was no point crying in bed and I do'nt want my partner to see how upset I am. This is his baby too and it's been such a rollercoaster ride. I need to be strong or I will never have the strength to try again.

Could this bleeding be a normal thing? Has anyone bled this early and been okay? If it is a mc how long will it take?

I'm not sure I can ever try this again, pregnancy seems to be about heartbreak and pain. I just do'nt know why or how other women can keep a baby safe and all of mine die.

Any help really appreciated.

thank you
