Husband thinks I’m pregnant!!!!

My husband and I have been trying for 3-4 months to have another baby... the first child was completely unexpected(was not trying to prevent either). Now that we are trying seems like it’s been more difficult anyways... I was ovulating either 27 or 29. We had sex like 2-3 days before on and around when I was.... on halloween out of know where he just looked at me and said I was “glowing” and thinks I’m pregnant. My boobs been hurting and belly been cramping some but I am not supposed to start till next week... what do y’all think??? To early to even think about it???
