What could cause a crater-like pattern on tonsils along with irregular sleep patterns in a 5-month pregnant female?

Hello doctor,

I am a 20-year-old Caucasian female and five months pregnant. I have two bumps on my tonsils maybe the size of a lentil or smaller. They look like cysts but they could also just be normal or something. I have enlarged tonsils since at least last year when I had some bouts of Streptococcus or something. I had been given antibiotics like Amoxicillin for Strep throat problems. I have a crater in my tonsils. Also, my tonsils do not really bother me (I do not think I have tonsillitis or anything) but I want to make sure there is nothing wrong with them. I have Medicaid and I do not know if I can see an otolaryngologist or not. My husband or I might be a mono carrier. I do not smoke or drink and nobody smokes around me ever.I just overcame a sickness with sneezing, coughing, stuffy nose, sore throat, etc. But, no fever, and sometimes I still feel a slight sore throat but it will go away soon thereafter. And I have a feeling it will go away altogether soon. Tonsil stones do occur kind a lot to me but I always get them out with a Q-tip and can make me bleed and my tonsils will feel sore after. I have crater tonsils. I am overweight and suffering from obesity. I have no children. It is painful to drink or eat anything. I have no family medical history, except slight mental health issues like depression, but nothing crazy. I like to eat poorly. I do not brush as often as I should, but I always get my tongue thoroughly, rinse with mouthwash, and I always at least brush whenever my teeth do not feel clean. I take Melatonin every night for sleep, one prenatal vitamin each night, and the lowest dose of the antidepressant called the tablet Effexor (Venlafaxine) every night as well. I have had pretty irregular sleep patterns lately. I have been sleeping all day and staying up all night. Thank you.
