Possibly Pregnant AGAIN

So my baby girl is 3 months old now she was my first and I’m STILL new to this mommy thing. My boyfriend and I originally wanted a boy hands down. We had always planned to have a son then a daughter maybe a year after. When that didn’t go well my boyfriend eagerly wanted a boy close to our daughter but we didn’t plan this close. I’m not sure if I’m pregnant but my calendar shows 3 days late for my period and we happened to have sex on my ovulation day ! All I’m praying is the Lord blesses us with a baby boy 🙏🏽🙏🏽🙏🏽 if it’s another girl my boyfriend says he is done with kids for a while! 😭😂 anyone here had a baby right after the other?? I’d love to hear about it btw this is my sweet girl hopefully a brother is coming soon🤞🏾
