Pregnant question...kinda long post

Sooooo I’m thinking I might be pregnant again...with my second... but I’m too chicken to take a test. My period is due in a little less than a week but my husband had an oops with the pull out method right around ovulation (that’s why we have our son) it only took 1 try and bam so I’m a bit concerned it may have happened again. I honestly would be thrilled to have another but also freaked out because my husband has anxiety issues and stresses enough with our first which in turn stresses me and our marriage. He isn’t that helpful with our son at this stage (I feed, bathe, change diapers, put to bed, wake up at night with our son etc.) I’m a stay at home mom so I’m alright with it but a second just seems crazy daunting with little to no help. Ok question...I am still pumping some only about 2-3 oz a day but just recently my supply has gone down to almost nothing...did any breastfeeding moms who got pregnant notice a change? Also my breast just started aching a lot today 🤦🏼‍♀️ I’m about to order some test strips off amazon to ease my mind before period comes.
