Make an appointment or No???

I had a ectopic pregnancy in October and had to receive a methotrexate shot. It’s been 3 months of ttc and still bfn. Lately in the morning, whenever I pee I’ll have just a tad pain in the lower part of my stomach. (Like a tight feeling in my uterus) I had my regular obgyn checkup in November and nothing was said anything was wrong. It just makes me nervous maybe like a cyst or blockage or idk. I don’t want to make an appointment and then look stupid if nothing is wrong. I have been having regular periods since the shot as well. I just don’t want to think something is wrong from me getting pregnant, but it may just be the case it’s gonna take awhile to get pregnant because of the whole ectopic pregnancy. What would y’all do??
