Clearly I'm new at this

Alright I missed my period . I've had a lot of cm which is out if the ordinary for me bec of breast feeding  , and other random symptoms that could go either way . Weird cramping sore boobs ect . For te past two days I've had a lot of watery cm but then a little big ago I notice the consesitenty had changed & it was more like the cm aroun time of ovulation . (Thick stretchy like egg whites) and me and my hubby had sex about 45 mins ago and at first it was a little uncomfortable my cervix felt very very low ... Anyone else ever expirenced this . I had a pinching pain in my side this morning ..?
