Skipped a period but forgot my pill also

So last month I was crap at taking my pill I missed at least 2 days and I did that about 3 times in that pack and I didn’t double up and I’m sexual active

But I went on holiday so I carried on my pill so I didn’t get a period

Now my boobs are in the worst pain ever and have been for 2 weeks but I only

Started my new pack less than 2 weeks ago

Help please? Could my sore boobs be because of my pill x
