Losing my mind

Samantha • I’m 28, single mom. Daughter is 7❤️
So everyone I know is coming up pregnant. Like in the last month I've had 4 people they were expecting and they were either not trying or preventing. Here I am, been ttc since Oct 2014 with #2 and still nothing. My husband and I want another baby. This will be his first. Also, I finally caved and ordered some ovulation kits and pressed. I just feel like it's not gonna happen :( my dd keeps asking me for a brother or sister & I'm just starting to lose hope... spent the last 2 months not tracking hoping that would help but nothing so far. Af was right on time this month. Ugh. Due again the 24th of March so we will see I guess
