strep throat and pregnancy?

I know that women tend to feel like they're getting a cold or getting strep throat before they get their BFP sometimes. The last time I had a pregnancy scare I thought I had strep throat but the rapid test and cultures tested negative, and then my period did end up showing three days late (not normal at all for me) and it was extremely heavy. I'm now having a lot of pregnancy symptoms (though it's still way too early to tell, only 7 DPO) and I went to the doctor for the same thing again, strep test negative but I definitely have white blotches on my tonsils. Is it possible maybe I miscarried way early on the last time this happened? I feel like I'm just being super paranoid and crazy, and maybe all the "signs of pregnancy" I think I'm feeling are just what I'm feeling because I'm sick.
Here's a list of what I've noticed is different this cycle: period 5 days early, very sexually aroused during ovulation, a lot of lotion/school glue CM around 1-5 DPO, now more watery/ewcm at 7DPO, light cramping (I NEVER cramp), fuller breasts, nipples tender to touch, neck/back pains, joint pain, increase in appetite, cravings for foods I'm usually not too into (lots of red sauce), frequent urination, and extreme fatigue.
I know there's a very slim chance of me being pregnant bc even though we didn't use a condom and we did have sex on the night of my most fertile day (according to CM checks), he pulled out and hadn't cum for at least a week before that night. I just feel like my mind and body are playing tricks on me.
