Looking for some advice - 3MC and trying for 1.5 years

So we’ve had our first blood test done at 3weeks 5 days and was 220- which the dr was happy with. Tomorrow we have our next one to see if it’s doubled. Problem is I’ve had tummy pains on and off all day. I wouldn’t say cramping pains which I know are common. More just pain?! I feel when I go to the loo I have a small relief from the pain (TMI!) but then it’s back?!

I’m nervous because I’ve had 3 MC and we’ve been trying for such a long time. I’m on progesterone suppositories and max pregnancy vitamins so I’m out of ideas what else I can do!!!

Any success stories from anyone who can relate would be amazing ❤️❤️
