Tick bite 4 weeks pregnant

I found a tick on me this morning. I’m not sure how long it was on there but it didn’t seem to be engorged nor did any blood or fluid come out when squeezed after removal. I’ve talked with my doctor and she does not seem to be concerned whatsoever. She says to monitor it, but since it didn’t seem to be on there for a prolonged period or time or be engorged, I shouldn’t worry too much. But, being pregnant I am absolutely terrified. I’ve had complications in the past with pregnancies and I can’t believe I finally get pregnant again and get bit by a tick!! I’m sure I may be over thinking things, but I honestly can’t seem to calm down.
