Anyone experienced this ??

So like 3 days ago started spotting because AF was coming but me and my SO just tried lube for the first time since then and been having sex everyday since we like it that much but I didnt bleed a lot like my period normally does only a little bit but now I have no period but last night when we had sex my vagina was in so much pain and it burned when I peed after. I also have irregular periods because the depo. But I feel like my period when away cuz of the sex and since we tried the lube.
