Early period.

Jo
I got my period exactly a week early last month and first two days where extremely light (Peach color and only sometimes when I wiped there was any color at all). Then I got actual red for the remainder of my cycle.  I get my period like clock work since I was 12.
My thoughts : ok that means I'm not pregnant carry on with life. 👍🏼
However now about 2 weeks after "period" I had sex and I got cramps the day  after and my back and insides are hurting ( like when you have to fart and you can and you feel all gassy). Delt with that and kind of had  wet number 2 for about 4 days. At this point I'm like I have to go to the doctor. 
THEN my boobs start hurting and it's the exact same pain of my last pregnancy (which ended in miscarriage back in September ) it totally took me down memory lane I even forgot I experienced this and it feels he exact same way . Now I think I'm could possibly be pregnant 🤰🏻 but I also don't even want start to think to get sad about it. Things just add up this time around. In fact I was over TTC,  counting and having sex a lot because I recently got my dream second job and I just told myself god will bless me when his best timing is. 
I don't even know what to think. I've had sex once since my "period" we don't use protection  and I stopped logging everything because like I said I'm not going to count anymore and stress myself about it then be sad when I get my period. 
I did buy dollar tree tests, all negative. However if I am it would be to early to tell from previous "period" and the 1 time we have had sex which was 5 days ago.... 
Side not my previous pregnancy I craved going to the gym and eating super super healthy and I seemed vey calm in situations that normally I would stress about. I also Had pregnancy glow. 
Yesterday my coworker asked if I. Had been squatting because my behind looks lifted, hard and plump 👏🏼 yay! And I been eating super healthy which is normally not easy for me. 
My questions is have any if you had a heavy early period with light start and still found out they  were pregnant when this was happening or it was the begging of a pregnancy? 
Thanks ladies. 😊
