Could this be it

Crystal
So me and my hubby have been trying for a little over a year now to have baby #1 but with my pcos it has been very difficult but I have been having a pretty regular cycle for the past 6 months and we have been having sex like every other day and in February no period so far for March no period and I had some dark reddish-brown mucous which is new and I don't know if that's normal or if it's a sign of pregnancy I haven't has nausea or anything slightly sore boobs and having a bunch of headaches but that's it. What do you think??
