ttc 13 months after c section

I am waiting for af to arrive on the 30th or 31st of this month.. I think I ovulated on the 16th just guessing because I am out of ovulation tests. since the surgery I have not had any feeling in my uterus area in awhile on the inside. like for example when I have a period I don't have any cramps just bleed a lot. so anyway I've only had about maybe 5 periods since I've had my baby and I nursed for 11 months. the last 2 periods have been kinda normal which makes me think I am finally ovulating again. & i am surprised that the last couple days I have had small twinges or cramping type pain in my lower abdomen. either I'm getting my feeling back or maybe it's a sign of early pregnancy??? I've also had a lil back pain today & today my breast seem fuller. which I should know because after breastfeeding they were flat as can be & so saggy.... they certainly seem a little fuller today which boosted my self-esteem some. Hope they stays this way lol. anyway I don't want to get my hopes up with anything because it's so early. But last pregnany I knew very early as well when I was pregnant.. so idk.. I'm just waiting to test now.. maybe will test around 10dpo lol. feeling impatient. any thoughts from other mommas that have been through this too? or just opinions?
