Period is 18 days late ..

My period has never been this late. 😫 little back story so I was on BC for 2 years and I got off last year in November. Got pregnant in December. Had a miscarriage in April and got a d&c. Got my period in June very light. Then I got it in July, August, and September on time. Then in October it was 10 days late and got it on day 11 after I took boric acid to treat my BV that I had going on. Now I’m November I completely missed my period making me 18 days late. I went to the gynecologist so I’m not pregnant but she said she doesn’t think I have PCOS. She wants to put me back on BC to see if that helps but I don’t want to go back on BC because of my previous experience and I want to try and have a baby next year. So I don’t know what has been causing my period to be so late last month and this month.

Not sure if it’s because I gained a lot of weight... after my miscarriage I feel into depression and was stress eating ALL THE TIME. when I got pregnant I weighed 170 now after everything I weigh 188... not sure if me gaining so much weight in 6 months is the cause because I’ve gotten my period on time after June but now all the sudden it’s gotten late.

I haven’t gotten any symptoms of my period coming but I have noticed my lower back has been bothering me and my lower abdominal where like you feel your cramps has been feeling weird. I haven’t been getting any cramps but when I press down it feels tender a little painful but not a huge pain like I would need to go to the ER.

And I have been getting yeast infections and BV back to back like 2-3 times a month. I have tried the antibiotics they given me last month then stopped and did boric acid instead. Than I got the antibiotics again and I have been taking them this week but haven’t been seeing much results.

Not sure if I should see another doctor because this one that I saw says for me just to go on a diet and eat better foods but she never ran any tests or did an ultrasound or blood work or nothing to see what could be causing it to be so late the only thing she says is for me to go on BC 😫
