Nervous...

I got my first postpartum period a little over a month ago & was due for the next period almost 10 days ago. I am still exclusively breastfeeding which I know can affect the cycle but still part of me is nervous that we might have had an “oops” which ended in me being pregnant again. Our baby is just ten months and we have three older kids... we were definitely done after our baby. The wait for a vasectomy is just horrendously long where we live (almost a year’s wait.. his appointment is in December! He made it in January or February). Bought a pregnancy test today and taking it tomorrow. Hoping my cycle is still just wonky from breastfeeding....but worried. Just needed to vent somewhere without panicking my friends or family haha.
