Need to vent

So my period was 3 days late...but it came. In those 3 days i was worried that i might be pregnant. I have a 3 month old son. First child. My husband admits to me that he was a bit sad when my period came because he wants another one already. Im so not ready. I was lucky to have my husband with me during the pregnancy...at the time he was looking for a job and now that he jas one he works 3rd shift and its almost like hes never here. Hes asleep or at work. Im not mad at him for that, work is work, money is money but it sucks. Hes parents live close but are moving this week so i wont have anybody to help. The only way i have ever gotten a break was by letting the grandparents watch him for a couple hrs. Bit nervous now i wont get a break. And worried when if ill ever be ready for another kid. I know i said four before my son came along and now right now i say after my son is potty trained but truthfully i dont know if i can. I cant imagine myself taking care of a kid and being pregnant with no help. Just needed to vent.
