7 months and weird abdominal pressure

I’m 7 months postpartum. I think at 4 months my husband and I started having sex and it was all good! Definitely felt different but not uncomfortable. Lately though I’ve been having weird abdominal pressure? It’s not pain but it’s like I feel bloated/like I’m full. Idk this hasn’t happened before I’m trying to see if it’s worth getting checked. Cancer runs in my family so my overthinking anything always thinks the worst
