3 months on Clomiphene 2 miscarriages and now 3 positives

After having my very first MC back in August 2015 I kinda gave up... but we really wanted another one..the Dr's did tests and said that I wasn't producing eggs every month like I should be so they wanted to try a fertility drug ( nervous, apprehensive, anxious and excited) I said yes... well we got pregnant on the 2nd month of taking it in April and had another MC ugghhh the devastation and defeat! What the heck is wrong with me?!? Now I already have 2 healthy children and people kept saying be happy with what you have when the time is right it'll happen...blah blah blah! All the stuff none of us want to hear when we are trying to conceive!! Well now it's May and my period is a week late...3 days late I took a test and it came back positive...excited but not getting my hopes up, then 2 days later took another, then yesterday another and I have a Dr's today... according to Glow I'm about 5wks
