Due to the mid-cycle of your bleeding you should see either your OB-GYN if they can see you today for an ultrasound and pregnancy test. If they can not see you today you should be seen in the ER for the same tests. Bleeding in the mid cycle, especially if you've been trying to get pregnant may represent a failing pregnancy or other potential complications. Most likely the first.
Did I answer your question to satisfaction?
You still do need an ultrasound if you are bleeding that much off your normal cycle timing.
Yes I would get this looked at today. With an ultrasound.
