TTC/fertility appointment?

My husband and I have been trying to conceive baby #2 for 8 months now since our MC in Jan. We have an 18 month old and this past month I got 4 +, one digital + pregnancy test but after a week I started bleeding and passed some tissue. So could have been a MC again, not sure since we didn't go to the dr and do any blood work. I just didn't want to be told your having a MC again when I figure we could put two and two together ourselves. So my question is, did anyone make an appointment with their dr to talk about fertility or help with getting pregnant? And what did they do or say or recommend? Any help would be nice. TIA!
