losing hope !! Sorry in advance !

Holly • 1 baby girl & 1 step daughter, pregnant with baby #2 😁💙👶🤰👣

I will start off with I never really thought TTC would be so stressful ! I had my first little one in 2013 and after I had her I went on birth control and decided to do Nexaplanon and was on it for 4 years and 5 months. I left my daughter's dad (sperm donor) because he was mentally and physically abusive, now with a great guy I absolutely adore and he adores me in return we make such a great team and he has 2 older girls one 12 and one 8 and of course my little one that is 4, and I finally got him talked into trying for a boy!!! YAY ! I got my implant taken out the end of February I believe it was and did as the ob said start taking prenatals and I should be but it's been a little over 3 months now and I don't even know how many test I have taken ?! I started my period just a day or 2 after getting it removed and then was dead on with the 28 days I started again. my cycles were always irregular before BC the my 3rd one I was just under a week late got my hopes up thinking we could be pregnant but nope ! just wondering if anyone has had a problem like this before or any advice ? TIA !!!! also i am 5'2 and 224 dont know if it could be my weight thats a factor or not because i got pregnant with my daughter quickly !
