Aspiring and bleeding mid cycle

Mary • Miscarried June 2014 and again September 2014. Got pregnant again in February 2015 and had a healthy baby girl. Now we are ttc for #2 since October 2016. Had chemical in April 2017 and still trying. Going through some testing now trying to see what to do
Hey all. I started taking baby aspirin 3 days ago after two reccurent miscarriages. Today I got up and had pink blood on my underwear. I had sex yesterday and I am around the time of ovulation. But I never bleed before for ovulation. Any ideas?
