I've called my Dr and they just told me to wait. My levels 2 weeks ago were 2.3 which is negative and normal. It's been 7 weeks since my MC and still no cycle. Last week during foreplay I had a little blood on my panties but nothing during intercourse or following. I've had some mucus like discharge similar to ovulation and again today with a little blood. I'm cramping like period or could this be a sign of implantation? Still eating faint positives as well. Thanks!
