TMI...cervical mucus during tww

So we are ttc baby #2. I don’t chart or use OPKs. I’ve just been trying to check cm. So my normal cycle is 28 or 29 days. We dtd cycle day 11, 13, 15 and 17. I’m currently on cycle day 20. Checked CM just now and found this?? What’s going on? I don’t think I had this with first pregnancy. I’m also having some very mild cramping.
