Pre baby size?

Theresa 🌙 • Hippy dippy mama. 😌
In 13 at 16 years old. I was 135 soaking wet. The same time I was pregnant with my oldest. 
I weighed in at 210 at delivery. 
I stayed 160ish this whole 2 years.  Until November time frame during my custody battle I dropped down to 120ish due to working, working out and being depressed. None the less I was a healthy 120 lol. 
Now at 15 weeks pregnant. I'm 170ISH I havnt weighed in a month. I just tried on my pants from my weight loss time frame in November. And THEY FIT. Don't button but they go past my thighs and booty. Which that's a lot to go past. 😂😂 
When I got back with my husband. (Don't ask lmao) I gained all my weight back! So I'm surprised they fit. 
What size where you before kids? Would you ever go back? Me personally. After his baby. I'm gonna work out my ab area. But I don't wanna drop less thethen 150-160
