Should I see a Dr?

Bryanne • I`m 24 years old. Been together with my fiance for 6.5 years. We have a 4 year old son and TTC #2, hopefully ASAP!! Baby dust to all!!
Hey ladies, need some advice. My SO and I have been TTC for 2 months now. In both those months I think I'm starting to see possible fertility issues. I get positive opks but my temps are confirming ovulation in any of the 3 apps I use. My average luteal phase is on 9 days which is to short for implantation. And to throw things way off one of my breasts started producing a little bit of colostrum. I haven't seen a gyn cause I didn't think they would see me due to not trying for 6mos-1 year. We have a son who's 4 years old so we know we can get pregnant. My question is should we see a doctor now or should we wait? Any suggestions would be great. TIA.
