A little unsure!

Hi everyone! New to this app. So I'm posting bc I have some questions that I can't seem to find the answers on the internet or within myself. Last month, I started my period June 17 and it lasted maybe 3 days. (Normal cycle is 30-32 days with 5-6 days lasting). During that time I got sick with a very bad flu bug that had me out of work and everything else for 2 weeks. Well anyway, in between then and now, I have been active with my fiancé using the withdraw method. I'm not 5 days late on my next period. I'm not sure if I'm pregnant or experiencing hormonal imbalances due to getting really sick a month ago!! I'm cramping a little, not painful. And my breasts are soooo tender. I've been a bit moody and ivebeen eating everything. If someone can help me atleast by just talking to me about potentially what's going on, I'd appreciate that a lot!
