Swollen lymph node right side of groin and pregnant

Ashley • Wife, pregnant with 1st Baby Girl DD 5/29/20

Hi guys, I just found out I was pregnant about 2 days ago and I am about to be 4 weeks pregnant on Sunday but today the right side of my groin started swelling up with like a lump under the skin and it is tender to the touch. I have gotten one of these before only about 2 or 3 times around the time of my periods and it went away the next day after it came up so I didn’t go to the doctor since it was gone. That is what I am hoping will happen this time but I am really worried cause I am pregnant. Has anyone had anything like this in early pregnancy??? 😫😭
