Feeding My Baby. Haven't Got My Periods Yet. Now Have Reduced The Frequency Of Feeding. Now When Wiped Felt A Lump In Vagina. Suggestions?

i had a baby 6 months ago and have just started my first cycle since being pregnant. So i haven't had a period in over a year. i am still breastfeeding so as i have weaned my baby over the last few weeks to only one feeding a day i expected to start any day. i was going to the bathroom and when i wiped it was almost like i felt a lump in the vaginal opening. i tried to feel in that area and i can't tell if it is just extreme swelling it is like the top of the vaginal opening if that makes sense. i know that you can have swelling in that area during your period but i have never had a lump like feeling when wiping. it is not painful at all and my period seems to be normal. should i get it checked or wait until my period is over and see if it has resolved.
