Period or ovulation i need advice ladies

Samantha • I am a proud momma of a 5 yr old Beautiful Smart Bright little girl Named Addisyn. I had a handsome boy last year named Declan. 💓 i love my life as a mommy xoxo

Hello so first My name is Samantha :)

I have two babies already

5yrs and 1yr :)

One girl one boy..

Baby#2 was conceived on birth control

And didn't show positive until over 5weeks

We are trying for baby #3

February 5th I had a good Period

Stopped February 10th

Had "baby time" on the 16th 17th

Had heavy bleeding the 18th-21st

And more baby time the

21st after bleeding stopped.

I took a test three days ago and was negative.

I do not know if I should count the mid cycle bleeding as another period or ovulation bleeding :'(

My breasts are sorta sensitive.

I'm nauseated and have gas.

We have been trying since November.

But some months I skip periods. :/

Help me.. :'(
