Fingers crossed, what do you think?

My husband and I had sex the before, during, and after my last possible ovulation time. This would've been after my last period in May (around the 24th). I had some very very light bleeding like a week or two after my period and was told it could possibly be ovulation bleeding. Then, about a week and half ago, I had some light bleeding and brownish bleeding that only occurred after I went to the bathroom and wiped. Today I'm feeling a little bit nauseous (which could easily be cause by nerves). I don't really track any of my dates or anything, but I was told it could be implantation bleeding. What do you think? Does it sound like a baby is in the works?
