I’m soo confused please help 😅😨

Hi all I just want to start off and say I’m currently TTC #2 ❗️❗️❗️😍😍😍 and this month I used opks for like the 2nd time I got a positive so we Baby danced and I’m now 4 DPO and seen a small amount of brown /pinkish discharge should I got to the OBGYN and get a pelvic exam ? To see if everything is okay with my baby maker Again it was very small amount I don’t think it’s IB because it’s to early for that to happen
