Need an opinion to calm down..

I had misscarriage on August 26th. The doctor said last Monday (Sep 15th) that I should wait 2 cycles to try again, otherwise I would have MC again. I had sex this Saturday and Sunday without condome. Doctor said that I probably will have my period in 2 weeks.. It may mean that I was ovulating that time??? My brests are sore and I had light pink spotting today (Wed).. Is this possible to be preagnante again?

Otherwise I would jump in happiness but now the idea of second possible MC is just depressing..

Any thoughts? (I'm 36 and possibility to become pregnate by Glow is 25%)
