Insight is welcomed

So I’m writing this just because I’m so confused with what is going on. Background, I’ve been off BC for a year and a half. Beginning of that, I experienced mid cycle bleeding but after consulting with my doctor, she said there was nothing to worry about. Probably a hormone imbalance from stopping BC. AF has always been on time maybe off by a day or two, but that’s it. On and off the BC.

My husband and I got married mid March and decided to TTC as soon as we said “I do”. First cycle I had some mild spotting, but nothing to write home about. Last cycle nothing but one day and it was so small I only noticed it in the bathroom once.

This cycle I started spotting CD 15. It is now Cd18 and it is still happening. It’s not enough to put in a liner or anything, but it is mildly alarming that every time I use the restroom it is there when I wipe. Also, this time I’m having some cramping pains, as well as just a pressure feeling every time I use the restroom. Obviously I’ve done a lot of research and it is not my friend, but my yearly exam is on the 28 of this month and I cannot push it sooner due to insurance purposes.

I guess my question is has anyone ever experienced this themselves? Is it normal for your body to experience this many changes when you first start TTcing?
