I can relate to the shock. We had decided that our 3rd was our last. I had maybe wanted to foster doing short term placements, but my DH wasn't for it. I also have known a little boy for over 2 years that my good friend has fostered since he was 4 months old (he's almost 3). If I could convince my DH I would have taken him in and long term fostered him... but my DH wasn't interested and really was done at 3.
I have PCOS and my other 3 kids were all fertility med babies. I had to use high doses of Femara and Metformin to O and it took a few months with each of them to get PG. I had been talking to my DH recently about getting his V and he was humming and hawing. Rightfully so. My fertility specialist told me I didn't need to take birth control full time. It was clear I only O on fertility meds (10 year history of being watched and monitored for Oing) so he told me to take birth control 3x a year just to get AF 3X a year to keep my uterus healthy. So that is what I was doing.
I had a period in November because of that, then nothing... totally normal for me. Then on a whim I took a PG test because I was having weird symptoms that I only get when PG. (Light headed, nausea, peeing lots, tender breasts) I was shocked that I saw 2 pink lines.
It took me two weeks to get it in my head I was in fact PG, that I was going to be a mom of 4, I am going to always have to drive a minivan, Family vacations are going to be more expensive and will be fewer and farther between. Sigh! It has sunk in now and I am getting excited.
I have given all the baby stuff away (except clothes for a boy) and I have no maternity clothes left. I still had 10lbs to lose, but was very much looking forward to being back into my size 0 jeans by fall. I would have. I maybe could have been back into them by the end of July. Now I am looking at having to buy maternity clothes and not being into my 0's again for at least a year and a half if not longer.
I get it. I get the feeling of being shocked and initially unhappy. I have excitement now and I am now looking forward to one last baby and I know although it wasn't our plan for us, it was God's plan for us. I know God has a better plan and I know I can trust his plan for us. I think that is what helped me feel excitement and know that I am going to be okay and that the baby stage (which is my least favorite stage) passes fast.
