Irregular cycle

Chelsie
My husband and I are TTC w # 3, but when we were trying this fall we had no luck. Discovered that my AF is jumping from 27 days to 33 days, which makes it difficult to pin point ovulation.
​What is frustrating is with our first two, we conceived first try. So, you can understand my frustration. I started thinking something was wrong and that maybe we can't have another.
​I decided to get on birth control to regulate my cycle and it isn't really coming at a regular day. 
​I'm done with my last pack and we are going to TTC, I'm going to use OPKs and take my temp.
​Just wanting to know if anyone else has this issue and what is your best advice to help us conceive?
