TTC: Pain After DTD

Stephanie • Mother of a sweet little boy (11/13/16) and little girl (08/30/2018)! 2 MCs (12/20/2015 and 7/25/2017)
In December I got pregnant for the first time but it ended after five weeks. During that time I had discomfort on my left side near I guess the pubic bone? It only occurred while sitting. We are trying again and last night I had some mild pain during DTD and it got worse after. More like a sore muscle but the same side I felt discomfort while pregnant. Yes I know you can't feel like your pregnant 2 DPO. I think I ovulated from that side but only because last time I ovulated from my right. Not sure what the cause is...Anyone else have discomfort. So worried I did something wrong. 😁😞 Can you compromise your corpus luteum? I know that is a stretch.
