Trying again

Hey ladies. I keep putting myself down, me and my boyfriend have been trying to have another baby for the past 2 yrs and nothing seems to work I follow this app for ov and it doesn't seem to work....my next step is to get my bf to check his sperm I've had all the test done on me and they say I'm good. I feel it's on me to I have to lose a few pounds been my heaviest since I had my daughter. just keeping my fingers crossed.
