pregnant??

So on February 4th I was supposed to start my period but all I got was pinkish cm slime, then February 5th in the morning same thing then in in the afternoon I just got clear/what slimy cm. February 6th I got a little bit of cramping with still the clear/white slimy cm. I ended up getting my period February 7 so I think, it's really light compared to what I normally get and today my boobs are so sore and when I think of any food I really want I can smell it. could I be pregnant? I had a miscarriage last March and a stillbirth this passed December and I just want my rainbow baby, is it me just over thinking things? what do you guys think?
