Bfp baby no #2 shaking!!!

So I decided to take a test this morning expecting a bfp. Periods have been all over the place and husband has had a seriously bad back so we haven't managed to "try" so expected the bfn diss appointment.... first test didn't seem to work so had to try for a second. Wasn't sure I'd got enough to make the test work - took ages for the test result to show and Boom! I'm shaking! Both tests look like the photo. We planned and I longed for baby #2 but now I feel so overwhelmed. I literally can't think straight will my little boy accept or hate a new baby. What if it's a boy, what if it's a girl (I only have boy stuff). Happy Monday folks I'm going to take it easy today I think l
