 [ Symptoms ] if you have swollen lymph nodes in your groin does having sex cause them to become even more swollen  my boyfriend is worrying over a possible hsv in his groin he had a worrying case a year ago as well but the doctor he went to lost his sample and is known to not be reputable his lymph nodes are swollen again but the few bumps he has look like ingrown hairs the lymph node swelling was going down last night so sex ensued but this morning they are even more swollen than the other day i am just wondering if when lymph node swelling is going down does having sex bring the swelling back up [ Disease ] hi yes it is possible to go through a whole pregnancy having periods but these would be shorter periods 3 days max ok tests try doing one with your doctor this way it would be a good way to go get every thing done at the same time get things organised ok just in case you are you do sound a bit iffy good luck
