feeling funny

me and my husband had sex last night. obviously, we’re trying to conceive and have a child. for some reason, i woke up this morning feeling, idk different. kind of off. i can’t really explain it. call me crazy, but i have no idea if this has anything to do w me maybe conceiving, or anything like that, i just wanna see if anyone else has had this happen?? idk maybe i’m going crazy.
