a lump/cyst near my vagina/inner thigh

Hi ladies. So apparently I have been having this boil/inside pimple near my inner thigh as seen in the image(yellow circle). Nothing is visible except that you can feel a lump there which is uncomfortable when I sit or sleep cause I got thick thighs and no thigh gap. Went to the doctor once and doctor said it was nothing but it keeps appearing once it was gone a few weeks/months later. I am pregnant now and I am worried this will affect my baby. I am only 13 weeks pregnant. Please help.
