Please give me a chance.

I'm 19 female 5'6" and 134-140 lbs. earlier this summer I was 125 and still not comfortable with my health, body, weight, so on. I monitor calorie intake and began lifting a 2 weeks ago.. Alternating between upper and lower body and I run about 3 times a week. I used to run everyday but with the weights and college starting back up I've gotten out of that routine. I only eat "healthy" foods. Frozen fruit (no sugar added) spinach, kale, eggs, salsa, grilled chicken, quinoa, rice(brown), and frozen to steamed veggies. That's literally all my diet is.. Oh and half an avocado almost everyday. I only drink water and green tea. No coffee no soda. I'm concerned that I've gained so much in two months (almost 10lbs) when nothings changed.. And over a week into doing weights and I'm already pushing 140 (NEVER BEEN THIS HEAVY IN MY LIFE). Help help help. Also been horribly bloated and gassy for about a week. What do I do? What am I doing wrong? Advice? You can see my body/ food choices for reference on my Instagram >>>healthyskinnyhappyfit<<<<
