I had a miscarriage 3 months ago and one regular period after. Following that I was one week late and during this time I had 2 positive pregnancy tests, although not a really dark line and then over the next few days lost the line and got my period 6 days late. I new that possible pregnancy was a problem as I had no breast changes at all, even normal period heaviness. I've had some uterine pain with running and at times pressure. About to ovulate again and wondering what is going on. Any ideas?

Hope someone can help.
