URGENT PLS HELP

I started the pill on the 6th of June and became sexually active a few days later, since then I’ve been having some abnormalities down there such as odour and discharge and penetration of any kind has hurt.

Before starting the pill it didn’t hurt at all.

I’m not sure if these things are to do with hormone changes or becoming sexually active as they both started close together.

I’ve had sex since and I’ve started to have some pinkish/brown discharge and minor cramps.

My next period would be due within the next week or so.

So I’m wondering if these things happening to me are because of starting the pill, because I would be due on or because im pregnant or something.

Last night I threw up about 30mins/an hour after I took the pill.

He has never finished in me

If someone knows what might be up pleaaaseee help because I don’t know what to do!!!!!
