Anyone expirence the same?! (Tmi no pictures)

Ok so I really hope I'm not breaking any rules if i am I'm sorry I'm new to posting! Anyways my hubby and I are not at this moment actively ttc but we don't stop it either. My fertile window said it should have started at 4/1 but I think it's off. I had ewcm from 4/2 to 4/5 ( usually only lasts a day if that) and we had sex on 3/31. Now I'm getting creamy clumpy white cm (no not a yeast infection or anything like that) and I have been gasy, have had an increased sex drive and appetite like you wouldn't believe! And I'm getting twinge in my lower abdomen and slight crampy feeling. I just started checking my bbt too so any advice on what maybe happened with your first children signs you noticed or maybe even advice on bbt and what they have looked like through your cycle. Just so I have an idea ( I know everyone is different, and nothing gets taken to heart). Thank you!
